Embodiment mono-:
For a better understanding of the present invention, below first two described two concepts:
Object border router: the object border router in the present embodiment refers to currently take this border router and the border router of other border routers is set as target;
Border router to be established: the border router to be established in the present embodiment refers to the border router corresponding with current object border router.

Be applied to the situation of Full-Mesh networking (being also full-mesh networking):
Under Full-Mesh networking, each border router has connection between any two, so the route that each border router is come from access interface will be published to other border router automatically; Under this networking, border router selection module is obtained the to be established border router corresponding with object border router and is comprised in current networking:
Judge the type of current networking, now judge that current networking is as full-mesh networking, other border routers in current networking are all the border router to be established of object border router;
Now target route generation module to should object access interface automatically generating target route on border router to be established is respectively:
Corresponding object access interface is respectively generating target route on border router to be established automatically, and the destination address of this target route is the object access interface place network segment, and down hop is the static routing of object border router.
Be applied to the situation of Full-Mesh FRR networking (being also the networking of quick heavy-route full-mesh):
Full-Mesh FRR networking is on the basis of Full-Mesh, to add FRR protection.FRR is also quick heavy-route; its protection philosophy is the main and standby relation that first configures a pair of border router; these two border routers have at least an access interface network segment identical; between main border router and standby border router, do not issue the route shielding, other border router configures respectively a main road to main border router by the standby route with to standby border router.As can be seen here, FRR is other protection of a kind of route level.A configurable multipair main and standby relation of L3VPN, also can form multipair FRR route protection.
Under Full-Mesh FRR networking, border router selection module is obtained the to be established border router corresponding with object border router and is comprised in current networking:

If object access interface is active and standby object access interface, the active and standby attribute of judgement object border router; If object border router is main border router, generative process is as follows:
In current networking, on every other non-current active and standby border router, automatically generate primary target route, the destination address of primary target route is the object access interface place network segment, down hop is the static routing of object border router, is also that its attribute is main static routing;
In current networking, on every other non-current active and standby border router, automatically generate alternate target route, the destination address of alternate target route is the object access interface place network segment, down hop is the static routing of the standby border router corresponding with this object border router, is also that its attribute is standby static routing;
If object border router is standby border router, generative process is as follows:
In current networking, on every other non-current active and standby border router, automatically generate primary target route, the destination address of primary target route is the object access interface place network segment, down hop is the static routing of object border router, is also that its attribute is standby static routing;
In current networking, on every other non-current active and standby border router, automatically generate alternate target route, the destination address of alternate target route is the object access interface place network segment, down hop is the static routing of the primary border router corresponding with object border router, is also that its attribute is main static routing;
If object access interface is not active and standby object access interface, generative process is as follows:
On other border routers in current networking, automatically generate target route, the destination address of target route is the object access interface place network segment, and down hop is the static routing of object border router.
Be applied to the situation of H-L3VPN networking (being also stratification networking):
Stratification networking can be described as again H-L3VPN, is divided into core layer border router (NPE) and convergence-level border router (UPE), and core layer border router is specially responsible for routing forwarding, management the whole network route; Convergence-level border router is mainly used to user's access, and management is attached thereto the route of equipment.In level L3VPN networking, can be divided into multilayer in theory, a convergence-level border router that border router is last layer, is again the core layer border router of lower one deck.The present embodiment for simplicity, is only described the most typical two layers of networking.H-L3VPN route issue rules: the access interface between core layer border router, according to full-mesh networking mode issue route, is also published to convergence-level border router simultaneously.The route of the access interface of convergence-level border router is published to all core layer border routers, but can not be published to other convergence-level border router.
Under H-L3VPN networking, border router selection module is obtained the to be established border router corresponding with object border router and is comprised in current networking:
Border router selection module is obtained the to be established border router corresponding with object border router and is comprised in current networking:
Judge the type of current networking, now current networking is stratification networking, judgement object border router is core layer border router or convergence-level border router, core layer border router in this way, and other core layer border routers in current networking are all border router to be established; Convergence-level border router in this way, the core layer border router in current networking is border router to be established;
Now the corresponding object access interface of target route generation module automatically generates target route and is on border router to be established respectively:
When object border router is core layer border router, on other core layer border routers in current networking, automatically generate target route, the destination address of target route is the object access interface place network segment, and down hop is the static routing of object border router;
When object border router is convergence-level border router, on core layer border router in current networking, automatically generate target route, the destination address of target route is the described object access interface place network segment, and down hop is the static routing of object border router.
