Hi My Everone please me some issue about MPLS-TE Path protection.
I've done on end to end configure, when main path go to down backup path working as well, but whe main coming up again the protection path still up, traffic not go to main path how we can do that, please help.
XR_A
Tunnel-TE40001
main path = XR_A to XR_B
protection path = XR_A -to- XR_C -to- XR_D -to- XR_E -to- XR_B.
XR_B
Tunnel-TE40001
main path = XR_B to XR_A
protection path = XR_B -to- XR_E -to- XR_D -to- XR_C -to- XR_A.
