DIS send HELLO interval ordinary packet router of 1/3 (default 3.3s ), which ensures DIS when a failure occurs can be more quickly found. Also called a pseudonode, it is a virtual router in a broadcast multi-access network, created by DIS. Explicit Route: 10.1.45.5 5.5.5.5 The Level 2 LSP contains all the prefix information that may be reached in IS-IS . Level1 LSP is only used in the local area. !! activation Tunnel of forwarding-adjacency R1(config-keychain)#key 1 The status of IP traffic engineering !

Do as shown in the F0/0 and Fa1/0 ports of R3 . In this way, even if the source destination address is unchanged, R3 will be at F0/0 and F1/0.

Ip address 10.1.45.5 255.255.255.0 Form a LAN adjacency: Each LSP has a maximum expiration time ( MaxAge ) in the LSDB . If this time expires, if no new LSP is received. Mpls ldp discovery targeted-hello accept from accept-ldp After the neighbor is discovered, the one with the highest transmission address is the active initiator. Note that here, the TCP handshake packet, the source address is the local Transport Address , and the destination address is the transport address of the peer . The transport address is the LDP Router-ID of the router by default . Therefore, it must be ensured that the two Transport Addresses are reachable.
