Interface loopback1 Network 10.1.23.3 0.0.0.0 area 0 PATHErr is actually sent to the headend router. The main reason for sending the error message is that the link used by the TE LSP fails, or the party LSR receives the PATH message with the forged message. Ip cef Local Circuit ID Local circuit ID is a link identifier. The identity of this circuit is assigned by the router that sent the Hello PDU and is unique on the interface of the router. At the other end of the point-to-point link , the local circuit ID in the Hello message may or may not be the same value.

Then if we configure: ISO10589 i L1 It has been verified by experiments. The global configuration command metric-style transition allows the original narrow metric to be smoothly extended to a new width. This command allows a router to accept and transmit both narrow and wide quantities. 10.1.34.0/24 [110/20] via 10.1.23.3, 00:00:01, Ethernet0/1 [Note] Label behavior of Frame Mode SSN ( send Sequence Number ): send serial number flag Clear text interface authentication The label mapping message advertised locally is meaningful to the local .

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. ! The port in TCP/IP .

DIS send HELLO interval ordinary packet router of 1/3 (default 3.3s ), which ensures DIS when a failure occurs can be more quickly found. Router-id 3.3.3.3 Manual re-optimization Priority 1 : 9375000 We may as IS-IS of level1 or level2 assign an interface authentication password. 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 , 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).
