Of course, there are other important functions, which will be explained later. 10.1.34.4 The routing table of R3 is as follows (omit direct route): Tracing the route to 55.55.55.55 Mlps ldp neigbor [vrf vpn-name] ip-addr password [0-7] pswd 15 Regional prefix replacement. As shown above, you want to replace the original area prefix 49.0001 with 49.0002 . To achieve this goal, configure an NSAP address for the new area prefix on A and B. Note that the SystemIDs of the two addresses must be the same. Then delete the areas of A and B in turn .

C . There is a small detail,is ccna easy to pass, noted that the distribution of the label no concept of split horizon, that although B may be from C to learn the route to X , but B still will be prefixed with X passed to the bundled label C . C will also put the label passed from B in the LIB , but don't worry about loops, because LDP can prevent loops by means of IGP routing protocol. RESV response PATH message, to establish and maintain LSP passage Bandwidth information IS-IS During the ES-IS work process, the end system sends an ESH ( ES Hello ) message to a specific address to notify the router of its existence. The router listens to the ESH packet to discover the ES existing in the network , so that the packet arriving at the specific ES address is subsequently forwarded to the ES . In ES-IS , the router advertises its own existence to the ES by sending an ISH ( IS Hello ) message to a specific address . ES also monitor ISH , if a plurality of received IS transmitted ISH , ES will then be selected, and sends all data to the IS .
