interface.
Conditions: Occurs when you configure two Equal Cost Multipath (ECMP) paths on a bridge
domain interface (BDI) using static routes.
Workaround: The following workarounds exist:
–
–

•
Symptom: Some interfaces within a bridge-domain are unable to send outbound L3 multicast
traffic.
Conditions: Occurs when the bridge-domain contains EFP interfaces, some of which are on a
port-channel. The issue can also occur after a router reload.
Workaround: Issue a shutdown/no shutdown on the BDI interface.
