Tunnel mpls traffic-eng autoroute metric 32 Outgoing MPLS TE component Clear text area certification Router ospf 1 Create a TE tunnel on R1 , the source is its own loopback0 , and the destination is 4.4.4.4 of R4 . Version:1 flags:0000 cksum:7931 ttl:255 reserved:0 length:132 302 If the LSP database is too large, send multiple csnp Type 1 length 12: Config Parameters: Choose the path with the largest " minimum available bandwidth " !! Use the dynamic calculation method to establish the tunnel PATH As a result, the size of the LSPDB is greatly reduced. Note that the above picture is just an abstraction and simulation concept. The ABCD four routers actually have ISIS adjacencies (in IS-IS broadcast). In the network, adjacencies are formed between routers of the same level on the same network segment, including all non- DIS routers. This is different from OSPF . However , after DIS , everyone The resulting LSP volume is reduced. That is to say, although all routers on the IS-IS broadcast network form an adjacency relationship,9tut ccna routing and switching, the synchronization of the LSDB is still guaranteed by the DIS . The LSP stability and reliability has been guaranteed. The operation of the SPF algorithm is naturally faster.
