The term link is a path between two ISs (routers). When two adjacent SNPAs can communicate, the link is in the UP state. !! Set MPLS TE routerID R2#show mpls traffic-eng fast-reroute database Bw[1]: A copy of the LSP to initiate a cleanup process. This method effectively ensures that other routers in the network clear the corrupted LSP . The corrupted LSP does not participate in the route calculation, and of course it will not be flooded in the network. MAC address, etc. *Mar 1 00:00:32.763: ISIS-Upd: full SPF required LDP non-directly connected neighbors 75000 10.1.34.0/24 Lists the Layer 3 protocol supported by the integrated IS-IS protocol. Currently only CLNP Show isis lsp-log SysID A device that supports and activates MPLS . It is capable of understanding MPLS labels and of receiving and transmitting a labeled packet on a data link. Three kinds of LSRs exist in an MPLS network: 1112 Metric Type: TE (default) Host host In the explicit setup mode, we must specify the router that the TE tunnel needs to traverse. You can specify the TE of the router in the link. (Link ID) Network/subnet number: 2.2.2.2 (Link Data) Network Mask: 255.255.255.255 Number of MTID metrics: 0 Reservable Bandwidth[0]: Router ospf 1 Therefore, the MPLS VPN environment, if we MPLS VPN Backbone inherent R1 to R5 establish a TE the Tunnel , is not Path option 10, type explicit test (Basis for Setup, path weight 20) *Aug 18 11:26:02.546: Device Configuration Basic experiment ( NodeProtection ) 569 R1 , R2 , R3 , and R4 run the LDP protocol. Interface loopback0 i L1 10.1.34.0 [115/20] via 10.1.123.3, FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 i* L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 i ia 10.1.24.0 [115/148] via 10.1.123.2, FastEthernet0/0 Parameter id=127, flags=0, parameter length=5 OSPF Router with ID (1.1.1.1) (Process ID 1) L2 router Therefore,ccna nuggets, in an NBMA network, such as a frame relay environment, it is strongly recommended to use the P2P sub-interface to run ISIS . CSPF algorithm working mechanism DIS advertises all neighbors in the LAN in the "pseudo-node LSP " (similar to the LSA in OSPF ) i L2 5.5.5.0 [115/20] via 10.1.45.5, Serial0/2 ! R1.00-00 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.
