Description (partial)

A Cisco router may see unicast traffic not being forwarded out of the Gig interface while multicast traffic is being processed by the router correctly. Pings would fail to a directly connected neighbour but OSPF would be up.

ASR 903 running IOS XE with BDI configs under the relevant Gig interface. Once we remove the BDI interface, we can see the issue.
