Look at the example above: A is in the area 49.0001 , B is in 49.0002 ,examcollection, because they are in different areas, so they become Level 2 adjacencies. Maintain adjacencies in the region at the same time. If A is configured: DN TE Metric is equivalent to the concept of weight value, note that this is to be distinguished from IGP metric Interface LDP discovery sources: Ip explicit-path name R3R4 enable next-address 10.1.23.3 Complete the routing information exchange between the area and the backbone where it is located, and assume both the responsibility of L1 and the responsibility of L2 .

Then the LSR pushes the IP packet into a tag header, tags 204 , and forwards it out from the F0/0 interface. In CISCO IOS , CEF switching is the only IP forwarding mode that can be used to mark messages . Therefore , CEF must be enabled on the router when MPLS is enabled . Area 2 -byte area identifier, also referred to as Domain from the upper portion (the portion defined HODSP is ) used to Domain ! Configure path protection on R2 and observe the phenomenon. We found that R2 can learn to R1 of the Loopback , R3 of the Loopback , and R3 directly connected interface routing of 34.0 , which is due to R4 pass R3 and R2 passed R3 of LSP did not carry the authentication information, then these LSPs to R3 after, R3 is definitely an error, so R3 will not flood the original LSP sent by R4 to R2 , and 3 will not flood the original LSP sent by R2 to R4 . However, R3 sends out its own LSP.There are R3 directly connected network segments 3.3.3.0 and 10.1.23.0 , 10.1.34.0 . These LSPs are flooded to R2 and R4 . Although LSPs carry TLV information for authentication , R2 and R4 do not open domain. Certification, so they directly ignore the certification information and then start reading LSP , which is the interpretation of the results of our experiments. Of course, if R2 and R4 are configured with domain-password but the password is different from other devices, then it goes without saying that directly discarding LSPs with different passwords will not be read at all.
