Folks,
Any idea how to remove this from the config?
router isis backbone
set-overload-bit on-startup 180
is-type level-2-only
! ISIS network number should be encoded with 0-padded loopback IP
! example:
! example:
net 49.0001.1921.2022.0222.00
I tried this, but to no avail...
RP/0/RSP0/CPU0:edge1(config)#clear comm
comment community-set
RP/0/RSP0/CPU0:edge1(config)#router isis backbone
RP/0/RSP0/CPU0:edge1(config-isis)#clear comment
RP/0/RSP0/CPU0:edge1(config-isis)# ! ISIS network number should be encoded with 0-padded loopback IP
Solved! Go to Solution.

Hi,
It looks like you are hitting CSCum68626
Symptom: The IOS-XR parser allows comments (Begun with !) to be added to an ACLs, interfaces etc. They appear before the ACL, interface etc. in the 'show running-config' output and there is no way to remove the comments, unless you remove and reapply the associated ACL, interface etc. Conditions: Workaround: Remove section of configuration, commit the changes and reapply without the comment. <B>Further Problem Description:</B>
Unfortunately due to the nature of the issue we will be unable to fix it, we would have to do a major overhaul of our parser in order to fix the issue.
Thanks,
Sam

Wanted to add a few more things to this. I didn't accept the close of this ddts and want to see it fixed.
A sw solution is beng worked on for this problem. Next time you check you'll see the DDTS in a non close state.
Although the workaround to remove the associated config portion is doable, it is not ultimate.
More to follow on this.

Thank you Xander. I would agree that removing ISIS in order to remove some comment lines is not ideal! :)

Xander,
Just wondering if this was ever resolved. We are seeing this behavior on our ASR9K's running 5.3.1.

Thank you Sam. I removed the net id and reapplied it, which happened to resolve my issue.
