The change has occurred. In the head router, this will record the labels along the way. 10.1.12.2 4 msec 0 msec 4 msec Signalling: connected 2 You can specify the ciphertext lsp authentication of level1 or level2 to carry the cipher text authentication information on the LSP . R3 found that the inbound tag 300 's tag package, the outbound tag is a POP , so he pops the top tag (actually a layer), and then directly throws the popped data to 10.1.34.4 , note that this time it does not need Find the FIB table again because there is already a next hop in the LFIB table. Eventually this data was passed to R4 . ATT/P/OL The configuration of R3 is as follows: We see that the main content of the pseudo-node LSP is the IS connected to this pseudo-node . Look at the neighbors of isis again : For example, this CEF shows that the data going to 4.4.4.4 is stamped with 203 and then sent to 10.1.12.2 .

When 5.5.5.0 is restored, then R2 will generate an LSP and set ATT again (this 5.5.5.0The route does not have to be an ISIS route. You can play it with a route pointing to null0 , and set the ATT .) One thing to note here are: tools used to match the recommended route prefix list, I was in 12.
