The router failed the setup - timeout I would guess.
No-ack is the response from ODL, indicating the router did not reply (as expected)

6056 2018-03-17 11:56:24.572 UTC root:createSRtunnel INFO: Create SR Tunnel response: {u'output': {u'failure': u'no-ack'}}

Next I would look in the router and see what it logs for pce.
For XR:

show mpls traffic-eng pce trace last 100

If you are using IOS-XR, what version?
What ODL version?

Cheers,
Nik

[mshehroze]

Below are the things your required. kindly advice the next step.

IOS-XR version is XRv 6.1.1
ODL Version is distribution-karaf-0.4.4-Beryllium-SR4

Note: I am using 2 Edge routers for which i have configured PCE peer. when path is being deployed it shows below error on pathman.
Response indicated the error in frontend-backend communication.

Logs for PCE on Edge Router:

I would recommend trying another version than IOS XR 6.1.1 and 6.1.2, I have seen the no-ack-issue with these.
As other releases work fine, I have not looked into why.

I don't keep a list of tested versions, but:

• 6.0.0 is fine
• 6.1.3 and later should be fine

Cheers,
Nik

Thank you for your support. i will try these tested versions and will revert if found any issue.

i have tried 6.1.1 and after configuring below command, everything is working fine. further can you please confirm if we can do auto failover using any bandwidth threshold or link/node failure( FRR).
