  • Cisco ASR 900 Series Aggregation Services Routers

Known Affected Releases

15.2(4)S1 15.3(3)S

Description (partial)

Symptom:
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.

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