LSP Router(config-router)# max-area-address xx It can be seen that we allocated 33M bandwidth for the tunnel with priority 6. The total reserved bandwidth of the original interface is 75M , and it is divided into 33M , so there is 42M . We can also see because we have modified the priority. The reservable bandwidth of the tunnel of level 6 is therefore lower, and the reserved bandwidth is also changed. Activate the MPLS TE tunnel feature on the interface. ! The composition of the router , Backbone must be continuous.

In operational contexts , a tunnel can be removed from one path and palced onto another. If it is a Frame Relay P2P sub-interface, then there will be no problem, this is the recommended deployment method. The tag value is 1 , and this tag can appear anywhere on the tag stack, except for the bottom of the stack.

Type 1 length 12: An intermediate system (which can be understood as a router) has at least one NET (up to 254 ) and the system ID must be the same. Cisco routers support up to three NET addresses by default , which can be modified using the following command: Interface 303 Et0/1 Thus, as long as 5.5.5.0 in R2 , then the routing table of R2 will, in its region to 49.0001 in flooding- LSP for the ATT is set, we can try to R5 of Loopback the shutdown , so 5.5.5.0 hung , and when R2 is detected this change, not found in the routing table 5.5.5.0/24 route, then R2 will trigger a LSP updates the LSP in the ATT not set, so a to R1 will only produce a Point to the default route for R3 . When 5.5.5.0 is restored, then R2 will generate an LSP and set ATT again (this 5.5.5.0The route does not have to be an ISIS route. You can play it with a route pointing to null0 , and set the ATT .) One thing to note here are: tools used to match the recommended route prefix list, I was in 12.
