GMRP	GMRP (GARP Multicast Registration Protocol), based on GARP, is used for
	maintaining dynamic multicast registration information. All the switches
	supporting GMRP can receive multicast registration information from other
	switches, and dynamically update local multicast registration information. Local
	multicast registration information can be transmitted to other switches. This
	information switching mechanism keeps consistency of multicast information
	maintained by every GMRP-supporting device in the same switching network.
	A host transmits GMRP Join message. 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.
	When the multicast source sends packets to its group, the switch only forwards
	the packets to the ports connected to 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.

Configuring GMRP The main tasks in a GMRP configuration are described in the following sections:

■Enable/Disable GMRP Globally

■Enabling/Disabling GMRP on the Port

■Displaying and Debugging GMRP

In the configuration process, GMRP must be enabled globally before it is enabled on the port.
