! MPLS TE considers the attribute parameters of the link (such as delay, jitter, etc.) All routers in a zone must have the same zone ID !! TE tunnel R3.02-00 2.2.2.2/32 0x4F65 Router-id 2.2.2.2 Next Hop !! Pay close attention to here Configuration command Level2 , using the interface level command: isis circuit-type level2 , then R2 and R3 will not advertise these direct links when advertising LSPs in area 49.0001 . So the routing table for R1 becomes: Hostname: R1 Router ID: Nterface fast0/0 mpls mtu mtu-size Do not advertise routes re-published from other routing protocols After the configuration is complete, we find that the adjacency relationship between R1 and R2 is UP , that is, the area authentication does not carry the authentication information in the IIH packet. Not only that, but the PSNP sent by R1 also has no authentication information, but the issued LSP has clear text authentication information. The experimental phenomenon is quite interesting. For R1 , all IS-IS messages received by R2 are not authenticated. R1 mainly focuses on LSP . It is found that the LSP sent by R2 has no TLV for authentication , so R1 ignores The LSP sent by R2 causes the routing table of R1 to be empty. However, although the LSPs sent by R1 are all with authentication information, R2 is not enabled.Area authentication, so R2 receives this packet,ccna question paper pattern, can also read, and can also use these LSPs , so R2 can learn the route of R1 .
