The registration and de-registration of membership results in the multicast
table being updated with a new entry or the existing entry modified.
This ensures that the networking device receives multicast frames from all
ports but forwards them through only those ports for which GMRP has
created Group registration entry (for that multicast address). Registration
entries created by GMRP ensures that frames are not transmitted on LAN
segments which neither have registered GMRP participants nor are in the
path through the active topology between the sources of the frames and the
registered group members.
