Every thing was working fine , The issue occur when I was testing the TE link.
Two TE was configured with mpls ip command.
In output of sh mpls forwarding-table, I found that it’s showing me POP TAG. (Was expected the same )
When I shutdown the both TE ( Tunnel interface ) on PE1 and unshut then I saw that next-hop was tunnel as same earlier & was in routing table also every this was correct but my VRF traffic was not passing through TE or through any other way . Because in routing table it was showing the next hop was accessible via tunnel. So it won’t take any other path. Entire communication was stuck.
All traffic was getting dropped. After investigating I found that in PE1 the output for sh mpls forwarding-table
The both tunnel was showing as Untagged [T] on PE1 & in PE2 it was showing POP TAG.
I cleared the mpls FIB counter but still issue persist. I reload that router and every this was working fine.
After reload it was showing me POP TAG on both routers.
Can any one explain what is the issue?
