Mpls traffic-eng tunnels mpls label range 300 399 The HELLO packet is sent to the multicast address 224.0.0.2 , and the source address is the interface IP. IS-IS supports two levels of routing: Level1 and Level2 . Level1 supports routing within the region, Level2 support routing between areas. The Level 2 LSP encapsulates the Level 2 network topology information obtained from the routers connected to the backbone network . The complete Level 2 network topology can be obtained by using the SPF algorithm in the Level 2 link state database . Since R2 and R3 do not run the BGP protocol, and there is no route for 5.5.5.0 and 6.6.6.0 in Core OSPF , the final result is *Aug 18 11:26:02.546: Peer LDP Ident: 2.2.2.2:0; Local LDP Ident 1.1.1.1:0 TCP connection: 2.2.2.2.31044 - 1.1.1.1.646 !

Router ospf 100 Switched Next Hop 3.3.3.3/32 LS age: 29 In the routing table, R3 goes to 1.1.1.1 and uses 10.1.34.4 and 10.1.23.2 equivalent load balancing. After the above configuration is complete,ccna pass for sure 2016, R2 will send LDP through the tunnel that has been established and reaches R4 . Note that the tunnel must activate the MPLS IP. The main function of the ES-IS protocol is to provide mapping of NSAP addresses to SNPA addresses for network devices . State: Oper; Msgs sent/rcvd: 26/22; Downstream Up time: 00:09:33 // Prerequisites for binding a label to a route prefix locally 75000 kbits/sec, The principle is similar to the plaintext interface authentication, but can be given HMAC-MD5 certification. ISO10589 Or Tunnel Id Intermediate system adjacent router Interface fast 0/0 R3.02-00 If there are multiple network Tunnel for different traffic services, it is possible that these tunnel importance of their degree of importance also vary depending on the influence of the actual business needs. Then if I configure a more important tunnel after a more minor tunnel , it may lead to the more important tunnel that cannot find an optimized or sufficient bandwidth path. We can avoid the above problem by tunnel priority .
