Packets are forwarded along the pre-established LSP . Then , after the tunnel is established,how many questions are in the ccna exam, how to import traffic into the MPLS TE Tunnel ? The traffic will only enter the LSP if it is on the tunnel . There are three ways: Level1 area 1 For this to work, adjacent LSRs must agree on which label to use for each IGP prefix., and each intermediate LSR must be able to figure out with which outgoing label the incoming label should be swapped BW (kbps) Access-list 1 permit 5.5.5.0 route-map test permit 10 Set-overload-bit You can see the main two contents contained in it: one is the directly connected network segment of R1 , here is 10.1.123.0 and 1.1.1.0 , and the other is the direct connection of R1 .

Label protocol uses LDP (default is LDP ) After saving the configuration and restarting, after the restart, the LSP generated by R2 is set to overload-bit first. This can be seen from the isis databse on R1 . We also enable debug isis update on R2 , and use show version | in uptime Check the startup time of the router. When the startup time reaches 120s , you can see from the debug information that R2 triggers an LSP and clears the overload-bit .
