[j-nsp] NSRP and igmp-snoop

if memory serves the NSRP communication is actually L2 Multicast, so yes enabling IGMP snooping on the switches for the NSRP VLAN likely will cause issues.  This same problem effects SRX clusters as well, if i'm not mistaken.  Presumably if you had an IGMP Querier on the VLAN then it wouldn't be an issue, but generally the only devices in the NSRP VLAN would be the two member firewalls.

Thanks,

Will
