Known Affected Releases
Symptom: Mcast traffic stops flowing over PW on changing the configuration. Traffic doesnt resume till reloaded. Conditions: Configuration changes should be such a way that BDI goes down and comes up. For example. consider the box has only EFP on bridge-domain 200 (EFP2) on interface gi0/0/5. service instance 2 ethernet encap dot1q 200 rewrite ingress tag pop 1 symmetric bridge-domain 200. show bridge-domain 200 -> should show only 1 port. if we remove this EFP now, the BDI goes down. when we add the config back, BDI comes up. So after BDI comes up the traffic doesnt flow. Conditions where bug is not hit. If the Router has 2 ports in the same BDI 200. the problem will not seen in this case, even if you remove 1 EFP and add it back.
