Router-id 4.4.4.4 The LSA is encapsulated into the LSU to advertise to the neighbor ISO protocol (data link type on Ethernet is FEFE ), in In this environment, all physical interfaces OSPF cost = 10 ,ccna cheat sheet, Loopback port cost = 1 The interface IP of R3 is 10.1.23.3 . Interface eth 0/1 The configuration of R2 is as follows (all configurations are omitted from the configuration of interface IP ): 10.1.123.0 is directly connected, FastEthernet0/0 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 The configuration of RouterB is as follows: 2 10.1.34.3 [MPLS: Label 303 Exp 0] 856 msec 1012 msec 1072 msec In the SWAP process, after the label is exchanged, the inbound label TTL -1 is then copied to the outbound label TTL . MPLS TE provides the following solutions: This NSAP address is still a bit longer, and it is inconvenient to use. The SystemID is mainly used to identify several attributes, such as adjacency information, LSP identifier in IS-IS database, etc. In most cases, We are more suitable for symbols that have literal meanings, such as R1 and R2 , rather than a string of numbers. So CISCO IOS provides us with a very good way: the mapping of the router hostname to the NSAP address. Essentially the mapping of hostname to SystemID . There are two methods of static mapping and dynamic mapping.
