[j-nsp] igmp snooping layer 2 querier breaks ospf in other devices

[Andrey Kostin]

Hi Aaron,

It's not clear from your explanation where l2circuits with ospf are 
connected and how they are related to this irb/vlan.
Do you really need a querier in this case? IIRC, querier is needed when 
only hosts are present on LAN and a switch has to send igmp queries. In 
your case, you have a router with irb interface that should work as igmp 
querier by default. Not sure if it helps though.

Kind regards,
Andrey
