In IS-IS , there are three in the HELLO packet: one is the interface point ( Point-to-Point the IS to the IS Hello PDUs ), one is LAN on to Ll Router ( Level-1 to the IS the Hello PDUs the IS LAN ), a method Is the L2 router on the LAN ( Level2 LAN IS to IS Hello PDU ) The configuration of R5 is supplemented as follows: Network 1.1.1.1 0.0.0.0 area 0 Mpls traffic-eng tunnels mpls label range 200 299 *Mar 1 00:00:32.759: ISIS-Upd: Important fields changed Interface Ethernet0/0 RFC 1195 The overload-bit will not be cleared until the BGP convergence is completed .

Is-type level-1 Show isis spf-log Activate the fast-reroute feature on R1 and observe the phenomenon R3 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 .
