Allows the headend router to rerouting when there is a problem with the link or node ,pass ccna test, and uses a temporary, pre-established path to bypass the point of failure.

There is a small detail, 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. Both data packets have the same format and each carry a collection of LSP summary information. The difference is that the CSNP carries summary information of all known LSPs in the link state database of the router , and the PSNP carries one of the subsets. To distinguish Level-1 , Level-2 link state database, the router generates Ll , L2 of independent SNP packets. *Aug 18 09:06:02.699: SENDER_TSPEC type 2 length 36: L2 rouer redistributes external routes into IS-IS 1.0.0.0/24 is subnetted, 1 subnets Ip address 1.1.1.1 255.255.255.255 R1(config-keychain-key)#key-string cisco R1(config-keychain-key)#exit Clear domain authentication A pseudonode represents a broadcast multi-access network (including all ISs connected to this LAN ), which actually "as a router" (above, gray router) in the network.

L2 rouer redistributes external routes into IS-IS Circuit circuit My Address: 10.1.12.1 The third layer destination IP matches the packet with the same specific prefix. Number of Links : 1 The penultimate hop pop-up mechanism has two types of labels, one is POP or implicit null , the label value is 3 in LDP , the other is explicit null , and the label value is 0 in LDP . If the tag value sent by the neighbor about a route is 3 , then when I send the data to the neighbor, I will pop the tag and transfer the inner data to the neighbor. If the neighbor has a tag value of 0 for a route , the local device will send a label ( zero ) to the neighbor and send it to the neighbor.
