Embodiment
The invention provides a kind of static routing based on intelligence and carry out the method that message is transmitted, need to be applied to the network system of deployment strategy route, this network system comprises route distribution apparatus and control point equipment, and as shown in Figure 1, this method comprises:
Introduce the static routing based on intelligence provided by the invention in detail below in conjunction with concrete application scenarios and carry out the method that message is transmitted.
In the method provided by the invention, at routing protocol packet, OSPF (Open Shortest PathFirst for example, ospf) protocol massages or IS-IS (Intermediate System toIntermediate System Routing Protocol, the routing protocol of Intermediate System-to-Intermediate System) definition color-attribute attribute in the message, this attribute is 7bit, and scope is from 0～128.The configuration routing policy corresponding on CCP equipment with the color-attribute attribute, control point equipment can generate static routing according to this routing policy, next of this static routing jump to be pointed to the next-hop device of expection, and disposes this static routing and have higher priority.For example, configuring static route on the CCP equipment:
ip?route-policy?policyl?permit?node?10
if-match?color-attribute?100
apply?create-static-route?next-hop?10.1.1.1[preference?2]
After generating static routing on the CCP equipment, have two routes that arrive identical address on the CCP equipment, one is original dynamic routing, other one is the static routing that generates according to routing policy.Original dynamic routing priority is lower, and state is inactive, and the latter is the static routing of high priority, and state is active, and therefore, CCP equipment preferentially carries out message according to static routing and transmits.Jump when unreachable when next of static routing, static routing was lost efficacy, and CCP equipment E-Packets according to original dynamic routing.
Carry out the method that message is transmitted in order more clearly to set forth the static routing based on intelligence provided by the invention, method provided by the invention is further specified below in conjunction with Fig. 2.
R1 is the route distribution apparatus among Fig. 2, and its related server provides two kinds of business: professional 1 and professional 2.When requiring the user capture below the R6 to walk path, R3 place, access service 2 at professional 1 o'clock, network configuration walks path, R4 place.In order to realize this routing mode, R1 is when the R.U.P message of issuing service 1 and professional 2, carry different color-attribute attributes respectively, the color-attribute that R.U.P message such as professional 1 carries is 0x01, and the color-attribute that professional 2 R.U.P message carries is 0x02.
Suppose that the direct-connected address of R3 and R5 is 10.1.1.1, the direct-connected address of R4 and R5 is 10.2.1.1, does following setting on R5:
ip?route-policy?policy1?permit?node?10
if-match?color-attribute?0x01
apply?create-static-route?next-hop?10.1.1.1?preference?5
ip?route-policy?policy2?permit?node?10
if-match?color-attribute?0x02
apply?create-static-route?next-hop?10.2.1.1?preference?5
If promptly to receive the color-attribute that the R.U.P message carries be 0x01 to R5, the generation next-hop ip address is the static routing of 10.1.1.1 (address that R3 and R5 are direct-connected); If it is 0x02 that R5 receives the color-attribute that the R.U.P message carries, the generation next-hop ip address is the static routing of 10.2.1.1 (address that R4 and R5 are direct-connected).
Under the Routing Protocol view, use these two strategies then.The Router ID that supposes R3 is 3.3.3.3, and the Router ID of R4 is 4.4.4.4, then:
peer?3.3.3.3?route-policy?policy1?import
peer?4.4.4.4?route-policy?policy2?import
After configuration finished, there were 3 in the route from R5 to business 1 with business 2: one is the dynamic routing that the R3 issue is come, its next jumping sensing R3; Article one, be the dynamic routing that the R4 issue is come, R4 is pointed in its next jumping; Also have one to be the static routing that dynamically generates according to routing policy, wherein next of professional 1 jumped and pointed to R3, and next of professional 2 jumped and pointed to R4.Because the priority of the static routing of configuration is 5, is higher than all the other two dynamic routings, therefore the route that comes into force at last is the static routing of configuration.
R5 is issued to routing table with this static routing, receiving behind the data message that R1 sends, purpose IP address search routing table according to data message, if purpose IP address is business 1 subordinate server of R1 association, then send datagram to R3, if purpose IP address is business 2 subordinate servers of R1 association, then send datagram to R4.
In the application scenarios of the present invention, R5 can also detect the route in the routing table, if find that next jumping of static routing is unreachable, then static routing is set to invalid or the deletion static routing, it is inactive that R5 is provided with the static routing state, the route of going business 1 by the issue of R4 dynamic routing protocol can activate now, and network convergence is very fast.
If R5 is known the IP address of the server zone that R1 hangs down and is changed, in order to guarantee the accuracy of routing policy, need to upgrade the message prefix in the prior art, be about to prefix and hang IP address after IP address before server zone changes is updated to variation down by R1.When R5 generates static routing according to routing policy among the present invention not needs consider the IP address of the server zone that R1 hangs down, therefore, when the IP address of the server zone of hanging under the R1 changes, if the business 1 that the server zone that R1 hangs down provides and professional 2 does not change, only need then to guarantee that the color-attribute attribute field property value in the R.U.P message of R1 issue is correct.
Static routing based on intelligence provided by the invention is carried out in the method for message forwarding, the field difference of the color-attribute attribute in the R.U.P message in dissimilar protocol massages.Introduce the color-attribute attribute below respectively at ospf protocol message, BGP (Border Gateway Protocol, Border Gateway Protocol) the interpolation field in message and IS-IS (Intermediate System to Intermediate SystemRouting Protocol, the routing protocol of the Intermediate System-to-Intermediate System) message.
During OSPF issue route, Different L SA (Link-State Advertisement, Link State Advertisement) corresponding protocols message defines different bit positions as the attribute flags position, is reached for the painted purpose of route classification.
The LSA of Type1 (first type) selects among each Link TOS position back 7bit as the attribute flags position, as shown in Figure 3; The LSA of Type3 uses the preceding high 7bit of Metric as the attribute flags position, as shown in Figure 4; The LSA of Type5 uses the 7bit of back, E bit position as the attribute flags position, as shown in Figure 5.In the attribute flags position purpose of flag attribute be for converge or nucleus equipment on, according to attribute next jumping of route is set, rather than next jumping is set according to prefix.Concrete, converge or nucleus equipment can directly be provided with next jumping, for example set ospf color-attribute 3 on the interface of message.When the LSA of type1 was converted to the LSA of type3 on ABR, directly its color-attribute position of copy was to the corresponding color-attribute of type3 position.The LSA of Type5 then need be when introducing be routed to OSPF, and the configuration routing policy according to prefix, is provided with the color-attribute position, can avoid configuration prefix list coupling route on nucleus equipment like this, removes to be provided with routing policy.
The color-attribute attribute flags has the prefix route of same alike result (comprising color-attribute) in the Update of BGP message, be bundled in the same Update message to send.The Update message as shown in Figure 6, the color-attribute attribute is put in the Path Attributes field, and revise the numerical value of Total Path Attribute Length simultaneously, and the attribute of color-attribute is optional, Transitive.
As shown in table 1, mark O is 1, and T is 1, and definition Attribute Type Code is 50.During the color-attribute attribute of Prefix Hierarchy Names, method is directly carried this attribute by routing policy with other attribute of definition BGP when issue in BGP.
