[Xorp-users] Xorp 1.5 can't add multicast vif

[Matt Stevens]

I'm trying to migrate a working config from 1.4 to 1.5, but running into 
the following problem.

This same config works fine on 1.4 - and I've tried starting with a 
blank config and adding bits in. As soon as I configure my plumbing 
things go south...

My running kernel is 2.6.18.8-0.10
