I don´t configured  a punt policies on the router, the punt policies are the default. Someone has experimentig this problem too?

yes you are correct there is no workaround for that (if you using the version mentioned in the bug)

but there is another thread user able to resolve the issue :

follow the thread and see if that helps (if not contact TAC raising a ticket, if that affecting any live services)

Thanks Balaji,

I searched if with a upgrade of the firmware to 16.06.07 (Cisco Recomended version) this bug was resolve, but i dont found documentation about this. Do you know if with a upgrade this problem resolve?

[balaji.bandi]

if you are able to upgrade to a new version as recommended with no service effecting, my suggestion to upgrading.

if this impacting your environment, and kit in smartnet, contact TAC for second suggestion.
