Chapter 1 GMRP Configuration
1.1 GMRP Overview
GMRP (GARP Multicast Registration Protocol), based on GARP, is used for
maintaining dynamic multicast registration information of the switch. All the switches
supporting GMRP can receive multicast registration information from other switches
and dynamically update local multicast registration information. Besides, local multicast
registration information can be transmitted to other switches. This information switching
mechanism keeps consistency of the multicast information maintained by every
GMRP-supporting device in the same switching network.
A host transmits GMRP Join message, if it is interested in joining a multicast group.
After receiving the message, the switch adds the port to the multicast group, and
broadcasts the message throughout the VLAN, thereby the multicast source in the
VLAN knows the multicast member joined. When the multicast source multicasts
packets to its group, the switch only forwards the packets to the ports connected to the
members, thereby implementing the Layer 2 multicast in VLAN.
The multicast information transmitted by GMRP includes local static multicast
registration information configured manually and the multicast registration information
dynamically registered by other switches.
