Describe through specific embodiment below.
Embodiment three
According to the embodiment of the invention, a kind of method for building up of transmitting of static MPLS tunnel of exempting to dispose is provided, as shown in Figure 7, its key step is following:
Step S702 is based on network element configuration default (promptly giving tacit consent to) MAC and default VLAN.Attribute based on whether the ether port arrangement " supports to exempt from configuration " defaults to and does not support.If be " not supporting " processing that then keeps original mode." support " attribute can only be at point-to-point ETH link, and does not use the logical segment layer, and uses under the non-butt joint situation, and promptly the service of connection devices port also will be opened and exempt from configuration feature.Exempt to dispose and be applicable to that putting in order net all supports to dispose in the network of this attribute this scene.
Step S704, configuring static MPLS tunnel is exempted from configuration on the webmaster, only specifies the physics outbound port, is unworthy of putting next-hop IP information, accomplishes the basic configuration in static MPLS tunnel, issues basic forwarding entry according to user configuration information.When judging that next-hop ip address is 0, think to exempt from the configured tunneling technique scene, obtain default VLAN and default MAC information as two layers of information of the correspondence in the forwarding-table item, form complete forwarding entry.
Step S706, form complete forwarding-table item after, the data message that sending ending equipment sends, the purpose MAC of its two layers of encapsulation are default MAC, source MAC is a port mac, the outlet message is a message of beating VLAN tag, VLAN is a default VLAN.The receiving device default port has two MAC, and one is the port mac of configuration, and one is default MAC, is one of message of these two MAC for purpose MAC in the message that receives, and then thinks correct message, carries out normal process.In like manner, when equipment is made label forwarding equipment, if find that next-hop ip address is at 0 o'clock, then be forwarded to the physics outbound port of configuration, the purpose MAC of two layers of encapsulation of its data message is default MAC, and source MAC is a port mac, and VLAN is a default VLAN.
Step S708, for TMS and SNCP protection, these two needs configuration next-hop IPs if outgoing interface then need not dispose next-hop IP for " configuration is exempted from support " yet.Exempt from the configured port on the basis; Every port is only supported 1 TMS; Transmitting terminal through protection in the configuration distributing next whether jump be whether 0 to distinguish be the TMS that the basis exempts to dispose, whether receiving terminal is distinguished for default VLAN through the VLAN ID (VALN ID) of message is the TMS that the basis exempts to dispose.Exempt to dispose default tag attribute through inquiry, fill default purpose MAC and VLAN establishment and transmit, send and receive detection messages.
Embodiment four
Fig. 8 is the sketch map according to the static MPLS tunnel networking of the embodiment of the invention, and is as shown in Figure 8, and this network is the networking that comprises PE1, P2, three equipment of PE3.On the port that needs on each equipment to use, enable to exempt from configuration feature; Configuration tunnel1 (path: PE1-PE2-PE3), bidirectional static tunnel on the equipment; During the configuring static tunnel only configured tunneling technique go out/inbound port, go out/go into label; Be unworthy of putting next-hop IP information, and pairing ARP of next-hop IP and MAC information.In networking as shown in Figure 8, the handling process in static MPLS tunnel is following:
When steps A, the network equipment start initialization, use and exempt to dispose default VLAN, default MAC comes to create automatically acquiescence three layer interface list items, be used for equipment exempt from dispose scene and transmit basically.
Step B; Configuring static MPLS tunnel on this network equipment is during configuration distributing, according to the situation of next-hop IP information; Integrate the different outlets packaging information: if next-hop IP exists, then corresponding ARP, the MAC of inquiry obtains VLAN, purpose MAC forms normal static MPLS tunnel and transmits; If next-hop IP does not exist, then fill default VLAN, default purpose MAC and form the tunnel of exempting to dispose scene and transmit.
Step C, the TMS that configuration exempts to dispose only needs the configuration detection port.When TMS information issues, equally according to protection next whether jump be 0 to judge whether to exempting from configuration, if for exempting from configuration, the packaging information (VLAN, MAC) of encapsulation affirmation just.Configuring static protecting tunnel group when protection group information issues, is used that the protection next hop information forms complete tunnel group information with the protection port among the TMS, and is set up the incidence relation of protection group and TMS, so that TMS renewal protecting tunnel group when changing.
Step D, layer service (L2VPN or L3VPN) in the configuration is exempted from configured tunneling technique through this.PE1 is last when being carried on this and exempting from business on the configured tunneling technique and mail to PE3; The skin of interior layer service is encapsulated as the default encapsulation of exempting from configured tunneling technique; When data message arrived PE2, normal reception (data message purpose MAC is default MAC information) also was forwarded on the PE3, finally was transferred to user side and received.
Step e; (TMS protection port needs consistent with the outbound port of protected tunnel when revising TMS protection port; And the modification of tunnel port information will be protected port modifications prior to TMS); Search related protection group information, trigger TMS and upgrade the protecting tunnel group, other associated services modules of linkage are upgraded outlet information.
From above description; Can find out; The present invention has realized following technique effect: the configuration data items of simplifying static MPLS tunnel; Only need to specify static MPLS tunnel physics outbound port, use default vlan, MAC information to set up transmitting of static MPLS tunnel, reduced the configuration error that configuration complexity and human factor cause.Exempt from configuring static MPLS tunnel and transmit when forming, need not related ARP information, transmit the formation performance and be superior to the formation of normal static MPLS tunnel, reduced the coupling between MPLS tunnel and ARP.Dispose corresponding tunnel of exempting to dispose and detect, exempt from configuration feature through the unlatching port and realize packet sending and receiving, thereby realize professional through the forwarding of static MPLS tunnel, measuring ability.
Obviously, it is apparent to those skilled in the art that above-mentioned each module of the present invention or each step can realize with the general calculation device; They can concentrate on the single calculation element; Perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element; Thereby; Can they be stored in the storage device and carry out, and in some cases, can carry out step shown or that describe with the order that is different from here by calculation element; Perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
