Symptom
IPv6 forwarding on individual vrfs is impacted after clearing IPv6 routes on multiple vrfs.
Conditions
Clear ipv6 route for multiple vrfs, in rapid succession, on multiple vrfs. For example:
clear forwarding ipv6 route vrf VRF349 * module all
clear forwarding ipv6 route vrf VRF399 * module all
Workaround
To avoid the problem, use 'clear forwarding ipv6 route *' instead of multiple 'clear fowarding ipv6 route vrf * module all' commands in succession.
To recover, perform shut/no shut on the affected vrf(s) to recover.
