GARP Multicast Registration Protocol (GMRP)
• GMRP propagates group membership throughout a network.
• GMRP allows end stations and SFTOS Switching devices to issue and revoke
declarations relating to group membership.
• (De)registration updates the Multicast Forwarding Database—multicast packets only
forwarded through ports with a GMRP registration.
• GMRP is disabled by default—user must enable GMRP for the switch and then for
individual ports.
• GMRP is part of the SFTOS Switching package and:
Interacts with the Spanning Tree Protocol, GARP, and the Multicast Forwarding Database
Requires Independent VLAN Learning
• There is an instance of GMRP for each VLAN.
• MAC addresses are qualified by the 2-byte VLAN ID.
• SFTOS GMRP complies with:
— IEEE 802.1D Clause 10
— GMRP port configuration and status table from RFC 2674
• SFTOS limitations:
— Default filtering behavior is not supported.
