Caveats in Cisco IOS XE 3.12S Releases
–
Deleting the last TEFP on a particular NILE (either 0 or 1 or both) and immediately configuring
EFP under the same port and for the same bridge-domain.
Workaround: Clearing multicast routes for the multicast group receiving duplicate traffic may
resolve the issue. Execute command clear ip mroute command to clear IPv4 multicast routes and
the command clear ipv6 pim topology to clear IPv6 multicast routes.
