Traffic is not switching within 50msec on shutdown of a link. (when OSPF is used as IGP)

1. Check if TI-LFA is enabled. If not enabled, enable ti-lfa and check if the problem is resolved.

2. Check if Backup FTN and ILM entries are installed using "show mpls forwarding table" and "show mpls-ilm table" respectively for FTN and ILM table

3. Check output for "show ip ospf tilfa-backup-path" and "show ip ospf tilfa-repair-list" to see if P and Q node are calculated and repair tunnels are calculated

4. Use "debug ip ospf tilfa" to debug further as needed.

Traffic is not switching within 50msec on shutdown of a link. (when ISIS is used as IGP)

1. Check if TI-LFA is enabled. If not enabled, enable ti-lfa and check if the problem is resolved.

2. Check if Backup FTN and ILM entries are installed using "show mpls forwarding table" and "show mpls-ilm table" respectively for FTN and ILM table

3. Check output for "show isis tilfa pq" and "show ip isis route tilfa" to see if P and Q node are calculated and repair tunnels are calculated

4. Use "debug isis tilfa" to debug further as needed.

All the entries are correctly showing but traffic is not switching in 50 msec within 50 sec

Check total number of labels on backup path including labels on repair tunnel. Number of transport labels should not exceed 4 and service labels should not exceed 2.
