For TE of OSPF extension ! !! Outbound label 201 , which is given by R2 Next-address 10.1.34.4 Network 5.5.5.5 0.0.0.0 area 1 Further analysis of the metric problem. We focus on 55.55.55.55 , after the basic configuration above, currently in the routing table of R2 R1 goes from R2 and then goes to tunnel . The cost of this path is cost=10+1+1=12 Experimental verification Therefore, we activate the forwarding adjacency feature on the CISCO IOS router, except that the TE tunnel endpoint router advertises the tunnel as a direct link, and also considers the tunnel when it performs the SPF algorithm calculation . And if we modify the IGP of the tunnel port Complete basic IP configuration (configuration omitted) Access-list 1 permit 5.5.5.0 route-map test permit 10 The Global Pool Sub Pool !! interface is the bandwidth pool for each priority tunnel R1 has already completed the collection of its own TEDB information,cisco ccna test online, and the calculation process of the tunnel path is completed on R1 .

Therefore, if you want to make the routing full, you need to add a re-release directly to R3 . OSI PDU 10.1.24.2 10.1.24.4 In this way, in the route of L2 , the route matched by the route-map will be injected into the level1 area , then R1 can learn 5.5.5.0 .

Only when the route-map match is established, the default route will be sent . The associated prefix list can be matched in the route-map to match the specific route prefix. The default route is advertised when there is this route in the R3 routing table. tunnel interface can be configured directly IGP Metric , for example, if the running OSPF , directly in the tunnel configuration mouth ip ospf cost can LSA The configuration of R2 is supplemented as follows: RFC 3567 Router-id 3.3.3.3 ATT/P/OL Configured on L1/L2 rouer, which is R2 , a default route is generated and flooded to R3 , but not to R1 . Intermediate System to Intermediate System (IS-IS) Cryptographic Authentication If a router has insufficient resources, it may not be able to maintain a complete link state database. Data traffic arriving at this device may not be able to be forwarded normally. Therefore, it has the ability to inform or alert other routers. The specific method is to It produces LSP in the Overload-bit set. It was set overload field that LSP does not diffuse in the network and is calculated by the overload routing the router will not use the LSP . In other words, overload router is bypassed transmission path ( Bypass ), and those with overload router as the last hop of the route (directly connected local network segment) involved in the calculation only. In addition, the white point is that the IS-IS router that receives the LSP can still generate a route to the direct connection of the overload router, but will not go to other destinations through this router.
