8.2.5 Description of GMRP
The GARP Multicast Registration Protocol (GMRP) describes the distribution
of data packets with a Multicast address as the destination address on
Layer 2.
Devices that want to receive data packets with a Multicast address as the
destination address use the GMRP to perform the registration of the
Multicast address. For a switch, registration involves entering the Multicast
address in the filter table. When a Multicast address is entered in the filter
table, the switch sends this information in a GMRP packet to all the ports.
Thus the connected switches know that they have to forward this Multicast
address to this switch. The GMRP enables packets with a Multicast address
in the destination address field to be sent to the ports entered. The other
ports are not affected by these packets.
Data packets with unregistered Multicast addresses are sent to all ports by
the switch.
Default setting: “Off”.
