The routing protocol in the IP network forwards the data packet according to the minimum metric principle.

In fact, an LSP is a path when a packet traverses an MPLS network or a part of an MPLS network. TLV134 : TE RouterID Untag will remove all tag headers and turn them into a pure IP message. Document number Link Link Tib entry: 10.1.12.0/24, rev 4 Se1/0 R1#show ip ospf database opaque-area self-originate Traffic Engineering (TE) automatic bandwidth feature adjusts the bandwidth allocation for TE tunnels based on their measured traffic load: After completing the above configuration,cisco ccna online, we find that the is-is neighbor relationships of R2 , R3, and R3 and R4 are UP . This is because the IIH package does not carry TLV information for verification . In addition, the routing table of R3 is empty. *Aug 18 09:06:02.699: 10.1.12.2 (Strict IPv4 Prefix, 8 bytes, /32) LSP Head, Tunnel0, Admin: up, Oper: up Src 1.1.1.1, Dest 5.5.5.5, Instance 30 Fast Reroute Protection: None !

Change to 33M 0 kbits/sec IP internal reachability information 75000 16 Area verification is actually the verification of Level1 area . After the area authentication is added to an IS-IS router, it will check the IS-IS packets it receives . If there is no authentication information or error in the packet, it will be ignored. The IS-IS packet generated by the device itself carries the authentication information. If the receiver does not have the configuration area authentication, the device can still learn normally after receiving the packet carrying the authentication information. The authentication information of the area authentication is only included in the LSPs packet. Other packets are not included.
