In the invention, the IPV6 routing prefix has simple disposition and wider application.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of processing method and device of IPV6 route prefix.
Background technology
Fast development along with the internet; The deficiency of IPV4 (Internet Protocol version 4, internet protocol version 4) is obvious day by day, to the problems of IPV4; Released its alternative IPV6 (Internet Protocol Version 6, internet protocol version 6) agreement.Compare with IPV4, the IPV6 agreement can provide more function, for example; Sufficient address space is provided, and the network configuration of stratification supports that the address disposes automatically; Numerous users can obtain enough addresses through the IPV6 network, thereby satisfies ever-increasing user's request.
The IPV6 address is divided into two parts, i.e. subnet prefix and interface identifier.Wherein, subnet prefix is used for route selection, and interface identifier is used to identify a network interface, and subnet prefix and interface identifier are formed an effective globally unique unicast address altogether, a kind of IPv6 unicast address form as shown in Figure 1.
Concrete, the address configuration mode of IPV6 is divided into state auto configuration mode and stateless auto configuration mode.
(1) state disposes automatically; Through DHCPV6 (Dynamic Host Configuration Protocol for IPv6; The DHCP of support IPv6) SERVER (server) provides IPV6 the address, and this mode lower network keeper can carry out tight control to the node in the network.
(2) stateless disposes automatically, and send announcement through using router to the node that can realize the automatic configuration of stateless, thereby obtain route prefix and other subnet information, and together with the effective IPV6 of the automatic structure of the interface identifier of this locality address.
As can be seen from Figure 1, no matter be that state disposes automatically or stateless disposes automatically, all need obtain route prefix and can generate effective I PV6 address, use this IPV6 accessed Internet then.And the dual mode that the route prefix of IPv6 address can pass through ND (Neighbor Discovery, neighbours find) agreement and provides obtains.
(1) router solicitation; The user initiatively sends ND RS (Router Solicitation; Router solicitation) message is asked route prefix, and ND NA (Neighbor Advertisement, the neighbor advertisement) message of responding through router obtains route prefix information.
(2) router advertisement, router according to ND route prefix list item regularly downstream network issue route prefix information, make downstream user can obtain route prefix normally.
In sum, IPv6 provides a kind of simple automatic distributor system, thereby route prefix is distributed to the user.But; Carry out initial route prefix at router and divide timing; Have no information can represent which type of route prefix the user needs; Promptly dispose for the edge network of IPv6, can only select the manual configuration routing iinformation guarantee edge device can be normally downwards the user issue routing iinformation, thereby make the user of extension down can accomplish the layoutprocedure of stateless address automatically.And for the IPV6 network design of complicacy, the manual configuration routing iinformation is very complicated, thereby makes and originally can use a large amount of IPV6 address user to receive great application limitations.
In the prior art, the deployment way of IPv6 address route prefix comprises:
Scheme one: the user realizes that through the mode of DHCPV6 state address disposes automatically and the configuration of route prefix; Be that the user dynamically obtains the IPV6 address through the mode of DHCPV6; And use the IPv6 address that DHCPV6SERVER provides and the distribution of route prefix, thereby can realize distributing based on each user's addresses and route prefix.
Scheme two: trunking analog DHCP V6 CLIENT (client) realizes obtaining automatically and the configuration distributing process of route prefix.As shown in Figure 2, the upstream Interface that trunking (switch) connects gateway is DHCPV6 CLIENT, and downstream interface connects the user, and upstream Interface belongs to identical VLAN (Virtual Local Area Network, VLAN) with downstream interface.Wherein, Upstream Interface dynamically obtains interface IP address through DHCPV6; This interface also can get access to route prefix simultaneously; And trunking is issued to the route prefix that gets access in the ND list item, automatically route prefix is handed down to descending user by the ND agreement, thereby realizes the automatic deployment of user's route prefix.
Scheme three: trunking is realized obtaining automatically of route prefix and configuration distributing process through the mode of authentication.As shown in Figure 3; Trunking is PPPOE (PPP Over Ethernet carries ppp protocol on Ethernet) CLIENT, and the upstream Interface of trunking connects certificate server; Downstream interface connects the user, and upstream Interface and downstream interface do not belong to same VLAN.Trunking carries the user profile on the trunking to the PPPOE SERVER that is used for authentication through the PPPOE verification process; And on PPPOE SERVER, set up user message table; After authentification of user passes through, dynamically obtain the IPV6 address through DHCPV6SERVER.Wherein, be to connect and the network site when dynamically obtaining the address, thereby can distribute different route prefix for different users through network that user message table is distinguished the user.
But; The defective of scheme one is: the user must use DHCPV6 state auto configuration mode can obtain IPV6 address and route prefix automatically; And in present IPv6 network environment; Most of user is the stateless user of configuration automatically, thereby causes scheme one to have bigger use limitation.
The defective of scheme two is: because the upstream Interface of trunking can only obtain a DHCPV6 address dynamically; Therefore the route prefix that obtains also is unique (being the network segment under the corresponding IPV6 address); Thereby make the trunking complete machine can only issue a route prefix; Be the division that complete machine is only supported a VLAN, can't realize multi-VLAN multi-user's complicated applications, also have very big application limitations.
The defective of scheme three is: trunking must carry out the PPPOE authentication; Otherwise trunking can't carry user profile to certificate server; Also just can't distinguish the user and carry out issuing of route prefix; The realization that is scheme three must be used with the PPPOE authentication, the very big application limitations of same existence.

Embodiment
Core concept of the present invention by trunking according to the network design information of subscriber equipment (for example is; Can be vlan information) (for example generate first relay messages; Can be DHCPV6 Relay-forward message); And first relay messages that will carry this network design information notifies the server to DHCPV6, is the user equipment allocation IPV6 route prefix that belongs to this network design information by the DHCPV6 server according to this network design information, and with the IPV6 route prefix through to trunking.
And after relaying equipment obtains this IPV6 route prefix; Store in the ND route prefix list item of self; When user equipment requests IPV6 route prefix or trunking initiatively issue the IPV6 route prefix; Route prefix discovery mechanism through the ND agreement is handed down to subscriber equipment with the IPV6 route prefix, thereby has accomplished the automatic deployment of IPV6 route prefix, has alleviated the workload that needs the manual configuration routing iinformation in the present IPV6 network design greatly; Convenient processing is disposed simply, need not be used with other Additional Agreement such as authentication, and application is more extensive.
Based on above-mentioned thought; As shown in Figure 4; The present invention proposes a kind of processing method of IPV6 route prefix, be applied to comprise in the system of trunking, the dynamic host configuration protocol DHCP V6 server of supporting IPv6 and at least one subscriber equipment, said method comprising the steps of:
The processing method of IPV6 route prefix proposed by the invention is the network environment to IPV6, the sketch map under the concrete application scenarios as shown in Figure 5.In Fig. 5, edge switch (SWITCH) connects gateway and subscriber equipment as trunking, generally can be divided into a plurality of network segments on this trunking, to guarantee multiple user's different demands.For example, in Fig. 5, divided 4 VLAN on the trunking altogether, wherein, VLAN1, VLAN2 and VLAN3 are connected downlink user equipment respectively, and VLAN4 connects upstream gateway (GATEWAY).Wherein, subscriber equipment is connected to gateway through trunking, and visit INTERNET, and subscriber equipment 1 belongs to VLAN1, is connected to trunking through PORT (port) 1; Subscriber equipment 2 belongs to VLAN2, is connected to trunking through PORT2; Subscriber equipment 3 belongs to VLAN3, is connected to trunking through PORT3; The upstream Interface of switch is PORT4, belongs to VLAN4, and trunking is connected to gateway through this port 4.
Need to prove; It doesn't matter for the quantity of extension subscriber equipment under processing procedure among the present invention and the VLAN; Just handle accordingly according to VLAN, each VLAN is modeled to a subscriber equipment, hanging a subscriber equipment down with each VLAN among the present invention is that example describes.
Among the present invention; Realize the route prefix configuration of trunking interface through the function that on trunking, realizes analog DHCP V6 RELAY (relaying) AGENT (agency); When the upstream Interface at trunking enables the IPV6 route prefix when disposing function automatically, will carry out follow-up operation.In addition, in practical application, trunking can enable the IPV6 route prefix according to preset period and dispose function automatically, for example, whenever enables an IPV6 route prefix through 1 hour and disposes function automatically, and carry out follow-up operation.
As shown in Figure 6, the processing method of this IPV6 route prefix may further comprise the steps:
In the process of structure DHCPV6 Relay-forward message, need to fill Option (option) 37 fields of this DHCPV6Relay-forward message.The content of in the Option37 field, filling is a network design information; The vlan information that this network design information includes but not limited to this trunking (for example; Be example to get access to the VLAN1 nodal information in this step; Then this vlan information is the VLAN1 nodal information), trunking bridge mac address information, and be other user-defined configuration information etc.
Concrete, the form of DHCPV6 Relay-forward message is as shown in Figure 7, and for DHCPV6Relay-forward message, the implication of each field is:
Msg-type:RELAY-FORW (12) promptly representes the type of message, when msg-type is 12, representes that this message is a DHCPV6 Relay-forward message.
Hop-count: relaying is crossed the number of the relay agent of this message.
Link-address: global address or site-local address, server is confirmed client place link through using this address.
Peer-address: the address (possibly be client or other relay agent) that last one of this message is jumped.
Option: wherein need comprise one " relay message option (being Option37) ".
Concrete; Because the network design information of having carried trunking in the Option37 field in DHCPV6 Relay-forward message; For example, vlan information (VLAN1 information), trunking bridge mac address information etc. are according to above-mentioned information; DHCPV6 SERVER can be known the network design characteristic of the VLAN1 of trunking, and distributes suitable IPV6 route prefix according to this network design information.Comprising in the network design information that vlan information is an example, when DHCPV6 SERVER gets access to from the DHCPV6Relay-forward message after vlan information is VLAN1, can be for belonging to the user equipment allocation IPV6 route prefix of VLAN1.
Certainly, in practical application, being not limited to according to vlan information is the user equipment allocation IPV6 route prefix that belongs to this VLAN; For example, the Option37 field can also be expanded according to user's needs, the residing more detailed information of the equipment of inserting; This information is user-defined configuration information; For example, equipment rack number, user's name, IP address, port etc., at this moment; DHCPV6 SERVER can be according to above-mentioned user-defined configuration information to user equipment allocation IPV6 route prefix, to satisfy the control granularity that different address is distributed.
Concrete, the form of DHCPV6 Relay-reply message continues as shown in Figure 7, and for DHCPV6Relay-reply message, the implication of each field is:
Msg-type:RELAY-REPL (13) promptly representes the type of message, when msg-type is 13, representes that this message is a DHCPV6 Relay-reply message.
Hop-count: from Relay-forward message, duplicate.
Link-address: from Relay-forward message, duplicate.
Peer-address: from Relay-forward message, duplicate.
Option: wherein need comprise one " relay message option (being Option37) ".
Need to prove that the prerequisite of carrying out above-mentioned steps 602-step 605 is the function that on trunking, has realized DHCPV6 RELAY AGENT.
Below will combine the sketch map that dynamically obtains the IPV6 address shown in Figure 8 to come at first to explain the realization mechanism of DHCPV6RELAY.Wherein, DHCPV6 RELAY need provide the message between DHCPV6 SERVER and the client to act on behalf of forwarding capability.Concrete, when client is dynamically obtained the IPV6 address, request message being sent to DHCPV6 RELAY, DHCPV6 RELAY converts this request message into the Relay-forward message, and is transmitted to DHCPV6 SERVER; DHCPV6 SERVER gives client according to Relay-forward message distributing IP V6 address; Send Relay-reply message and give DHCPV6RELAY; DHCPV6 RELAY converts Relay-reply into corresponding Advertise or Reply message and is transmitted to client, thereby accomplishes the application IP addresses process of an IPV6.
Based on the realization mechanism of above-mentioned DHCPV6 RELAY, below will specify the realization mechanism of employed DHCPV6 RELAY AGENT among the present invention.In DHCPV6 RELAY AGENT; Need go up additional option information at DHCPV6 request message (being DHCPV6 Relay-forward message); So that DHCPV6 SERVER can be more the attribute of accurate judges equipment; Thereby according to corresponding strategies is this user equipment allocation IPV6 route prefix, and the option number of this option information is 37, i.e. Option37.
Concrete, the content that comprises among this Option 37 is as shown in Figure 9.And among the present invention; Can pass through Option 37 option informations; Notify the vlan information of this trunking, the mac address information that equipment interface is corresponding etc. to DHCPV6 SERVER; So that DHCPV6 SERVER can be user equipment allocation IPV6 route prefix and other relevant configured parameter according to this option information and corresponding strategies, thereby more strict control subscriber equipment has been realized user's difference management more accurately to the visit of Internet resources.
In form shown in Figure 9, the implication of each field comprises:
option-code：OPTION_REMOTE_ID(37)
Option-len: the total length of whole option.
Enterprise-number: the enterprises registration sign indicating number of network provider.
Remote-id: user profile, can fill MAC Address, perhaps other customized information.
Generally, can add relevant user profile, give unnecessary details no longer in detail at this according to user's needs.According to above-mentioned information, DHCPV6 SERVER can know that subscriber equipment is connected to the network from that VLAN of which equipment, thereby distributes suitable IPV6 prefix according to the residing network site of subscriber equipment.
Under this application scenarios, when all the VLAN nodal informations in the VLAN chained list do not travel through completion, then need forward in the step 602, obtain next VLAN nodal information (for example, the VLAN2 nodal information), and continue to carry out follow-up operation.
When subscriber equipment to trunking request IPV6 route prefix or trunking during to subscriber equipment proactive notification IPV6 route prefix, this method also comprises: trunking is notified route prefix information to subscriber equipment through the ND agreement.
Concrete, when subscriber equipment to said trunking request IPV6 route prefix or said trunking during to subscriber equipment proactive notification IPV6 route prefix, trunking need obtain the corresponding vlan information of subscriber equipment; And judge whether stored the corresponding IPV6 route prefix of vlan information in the ND route prefix list item; When judged result when being, trunking is handed down to subscriber equipment through the route prefix discovery mechanism of ND agreement with the IPV6 route prefix; Otherwise trunking obtains corresponding IPV6 route prefix according to vlan information to said DHCPV6 server.
Further; This trunking can be handed down to the subscriber equipment under each interface with route prefix information through the route prefix discovery mechanism of ND agreement; So that the subscriber equipment in the different segment can get access to the route prefix information of the corresponding network segment, thereby accomplish the trunking automatic layoutprocedure of stateless address of the subscriber equipment of extension down.
The ND agreement of IPV6 provides the discovery feature of route prefix, and wherein, the discovery feature of route prefix is the process that main frame (being subscriber equipment) is found one group of IPv6 prefix on the link-local, and the address that is used for main frame disposes automatically.The ND agreement provides the update method of two kinds of route prefix, is respectively: (1) host requests triggers the mode of router (being the trunking among the present invention) announcement.
When host-initiated, main frame can send the RS message by all routers in the link-local scope, and triggers neighbor router response RA message.After main frame is found the router on the link-local, dispose default router automatically, set up default route table, prefix list and other configuration parameter is set.Host requests shown in figure 10 triggers the sketch map of router advertisement, has shown among Figure 10 that the RS message triggers the process of RA notification packet.Wherein, the link layer address of HostA is 000D-88F8-03B0, and link-local address is FE80::20D:88FF:FEF8:3B0; The link layer address of Router A is 00E0-FC86-D6C4, and link-local address is FE80::2E0:FCFF:FE86:D6C4.Host A as source address, sends the multicast address FF02::2 of a RS request message to all-router with link-local address; After router listened to this message, the link-local address of using this host A send the multicast address FF02::1 of RA message to all nodes, thereby host A had obtained the relevant configuration information on the router as source address.Correspond among the present invention, through the corresponding processing mode, subscriber equipment 1, subscriber equipment 2 and subscriber equipment 3 can get access to route prefix information separately from trunking through the mode to trunking request IPV6 route prefix.
(2) router regularly sends the mode of router advertisement.Router periodically sends the RA message, so that main frame is found router and configuration information thereof on the link-local, main frame can be safeguarded other parameter of default route table, prefix list and configuration according to these contents.Router shown in figure 11 regularly sends the sketch map of router advertisement; Router-A uses the link-local address FE80::2E0:FCFF:FE86:D6C4 of self as source address; The multicast address FF02::1 of all nodes is as destination address; / 64) the transmission RA message of (default value is 200 seconds) is periodically announced self prefix (4000:: configuration information such as.Then, listen to the host A of this message and IPv6 global address or the site-local address that host B can dispose self according to this configuration information.Correspond among the present invention, subscriber equipment 1, subscriber equipment 2 and subscriber equipment 3 can get access to route prefix information separately to the mode of subscriber equipment proactive notification IPV6 route prefix from trunking through trunking.
Therefore; The update method of the route prefix that provides based on the ND agreement; Trunking can will be kept at local prefix through the prefix auto discovery mechanism that the ND agreement provides and upgrade to corresponding user equipment automatically, thereby the route prefix in the realization IPV6 network plan is disposed automatically.And pass through above-mentioned steps; Subscriber equipment 1, subscriber equipment 2 and subscriber equipment 3 all can get access to corresponding IPV6 route prefix information; And generate the unicast address of IPV6 jointly, thereby IPV6 the address process of configuration, accesses network have normally automatically been accomplished automatically with link-local address.
Need to prove; After the IPV6 route prefix obtains completion; Trunking can also judge whether the IPV6 route prefix needs to upgrade, and when the IPV6 route prefix need upgrade, trunking need obtain the IPV6 route prefix to said DHCPV6 server according to the corresponding vlan information of this IPV6 route prefix; Acquisition process and above-mentioned steps are similar again for this, repeat no more at this.For example, every through enabling an IPV6 route prefix in 1 hour when disposing function automatically, when the enabling of first hour, VLAN1 and VLAN2 have got access to the IP route prefix, and VLAN3 and VLAN4 do not get access to the IP route prefix; When the second hour enable, need judge whether the IPV6 route prefix needs renewal, and at this moment, VLAN1 and VLAN2 do not need to obtain the IP route prefix once more, and VLAN3 and VLAN4 need get access to the IP route prefix.Again for example, when upper-layer protocol is made amendment to the IPV6 route prefix or deleted, also need judge whether to need to upgrade the IPV6 route prefix.
Shown in figure 12, the present invention proposes a kind of trunking 13, be applied to comprise that said trunking comprises in the system of trunking, DHCPV6 server and at least one subscriber equipment:
