Greetings
I have the below topology for which am trying to deploy MPLS TE FRR (Link protection) on IOS XR.
CE1 – PE2 – P3 – PE6 – CE7
| | |
P4 P5
Nothing special about the deployment , static routing running between PE and CE for VRF transport.
The main concern is PE6 (Which is IOS XR based).
The active tunnel is tunnel-te0:
interface tunnel-te0
ipv4 unnumbered Loopback0
autoroute announce
destination 10.1.100.2
fast-reroute
path-option 1 explicit name PATH
The backup tunnel is tunnel-te1:
interface tunnel-te1
ipv4 unnumbered Loopback0
autoroute announce
!
destination 10.1.100.2
path-option 1 explicit name REPAIR2 protected-by 2
path-option 2 dynamic
The REPAIR2 explicit path is to exclude the link between PE6 and P3
The active tunnel is working fine (Trace between both CEs is functioning well).

Is there anything missing?
Note : MPLS LDP is enabled globally to ensure LFIB population.
Appreciated.
