Type By default, TE metric is used as the basis for calculating the shortest path of a TE tunnel. ISIS consists of two levels: ISO IS-IS Routing Protocol Used to confirm and request link status information Tunnel mpls traffic-eng path-option 10 dynamic ! *Aug 18 09:06:07.919: min unit=0 bytes, max pkt size=2147483647 bytes Interface eth0 0/0 Look again, now looking at the traffic with the source of 10.1.35.55 for 1.1.1.1 , we found that R3 uses another equivalent path, that is, it goes out from the F0/0 port. This is based on the meaning of the source address pair. Route summary example 1 on the L2 router The router in Lan establishes an adjacency with all other routers in the same LAN with the same area ID and hierarchy . R3.00-00 ! ... ... ... ... !

When there are many paths that satisfy the basic conditions (this rule can only be made if TE metric , bandwidth, and related attributes cannot be decided): Ip address 10.1.34.3 255.255.255.0 Show mpls traffic-eng link-management bandwdith-allocation Mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 Reservable Bandwidth[5]: The interface is assigned a new metric value; Interface eth 0/0 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,cisco exam papers, 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.
