MPLS TE between IOS and IOS XR

[Mohideen Pitchai]

Dear All,

I am currently running a lab on VIRL 2 (CML) where i am unable to establish MPLS TE between IOS and IOS XR..

i am getting the following error..i am using default bw, affinity with dynamic path selection. 

*Jan 12 08:34:17.809: TE-PCALC: Tunnel0 Path Setup [0000.0000.0022.00] 22.22.22.22: (isis level-1)

*Jan 12 08:34:17.810: TE-PCALC_PATH: No Path

IOS : 4.4.4.4

interface Tunnel0
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 22.22.22.22
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng path-option 10 dynamic
no routing dynamic
end

Appreciate if i can get further advice on how to move forward.

Thanks

Hey,

do you see RSVP messages make it to the IOSXR side? Could you post "show run | s router isis" ? Have e you tried deleting the tunnel and configuring it back? Are the log messages always the same?

Hi Ioris,

Thanks for your response.. Yes the log messages are always same on IOS side. I couldnt perform probably right debug command to get the path events at IOS XR side which is the next directly connected router (Midpoint).

I have tried to delete the tunnel and recreate , still the same behavior.. Below is the output for your kind reference.

router isis
mpls traffic-eng router-id Loopback0
mpls traffic-eng level-1

R4 (IOS - 4.4.4.4 - Headend) - XR1 (11.11.11.11 - IOSXR-Midpoint) - XR2 (22.22.22.22 - IOS XR - Tailend)

Above is FYKR.

Thanks

Mohideeen.
