LSPs are represented by LSPIDs , such as R1.00-00 . This R1 is the hostname of the device . Here we have the default hostname mapping mechanism. See above. . In addition , 00 after R1 is a pseudo node identifier, and 00 means that the originating router of the LSP is not a DIS , and then the last 00 is a fragmentation flag. Note that at this time, although the LDP adjacency between R1 and R2 has been broken, in principle, LDP does not adjacency, in the case of synchronizing, Designated IS ( DIS ) This TLV by L2 router establishes a virtual link through a backbone network between !

Integrated IS-IS and OSPF are 20 century 80 late-defined, which is about 1988 years. OSPF actually evolved from an earlier version of IS-IS , but it uses IP as a precondition. The core concepts of OSPF , such as the proliferation of link state information, the SPF algorithm, and the use of designated routers in the broadcast link, are borrowed from the IS-IS early version.

If level2 is not specified , the default level1 authentication. If the interface is enabled for plain text authentication, the password is inserted into all IS-IS packets: IIH , LSP , CSNP ,ccna certification practice exam, and PSNP (based on a specific level ). When actually capturing packets on the CISCO device, it is found that only the password information of the plaintext is carried in the IIH (placed for authentication).
