I am having a problem with multicast packets not being delivered accorss a Fram connection. It works ok if I remove the Multicast Stub config,
BB2--R3---R1--(FRAME)--R5--CLIENT
The traffic is being sent from BB2 and get to R1 fine. Here is some output from R1:

I think R5 is silently dropping the traffic or even tough R1 says it is sending it is not. Not sure...
On R5:
