Multicast memberships aren't in the neighbor table. The
neighbor table is for translating protocol addresses to
MAC addresses and that translation is fixed for multicast
destinations.

You can see group memberships with "netstat -g". There are also
some data in /proc/net/{dev_mcast,igmp6,mcfilter6} depending on
what you're looking for.
