The level2 route is injected into the level1 area , and these level2 routes can be summarized on the L1/L2 router . The configuration is as above. 75000 Section LAN ID as 1921.6811.1001. 03 . " the routers connected to the multiaccess network (Ethernet) all have the same circuit ID . The circuit ID is a one-octet number that the router uses to uniquely identify the 5.5.5.5(0) Redistribute isis ip level-2 into level-1 route-map test Complete basic IP configuration (configuration omitted) Keep priority 5.5.5.5/32, version 22, epoch 0, cached adjacency 10.1.34.3 R1#show mpls traffic-eng tunnels 10.1.34.0/24 [110/20] via 10.1.23.3, 00:00:01, Ethernet0/1 When the tail router receives the label request object, it will assign a label to the tunnel LSP and pass the label. !

Each zone in the IS-IS domain has a unique Level1 link state database. The shortest path is calculated by the SPF algorithm. 0 kbits/sec Another example of causing IGP and LDP to be out of sync is that when the LSR is restarted, the IGP can quickly establish an adjacency, and the LDP session may be set up slowly, that is, the necessary information is loaded in the LFIB . IGP forwarding has already begun before the correct label exchange . The message may then be forwarded incorrectly or dropped somewhere after entering the MPLS network.
