GMRP CONFIGURATION
GMRP GLOBAL CONFIGURATION
The following sections describe how to configure the GARP Multicast Registration Protocol (GMRP).
GARP Multicast Registration Protocol (GMRP) is a Generic Attribute Registration Protocol (GARP) application
that provides a constrained multicast flooding facility similar to IGMP snooping. GMRP and GARP are industry-
standard protocols defined by the IEEE 802.1P.
GMRP provides a mechanism that allows bridges and end stations to dynamically register group membership
information with the MAC bridges attached to the same LAN segment and for that information to be
disseminated across all bridges in the Bridged LAN that supports extended filtering services. The operation of
GMRP relies upon the services provided by the GARP.
GMRP software components run on both the switch and on the host. On the host, GMRP is typically used
with IGMP: the host GMRP software spawns Layer 2 GMRP versions of the host’s Layer 3 IGMP control packets.
The switch receives both the Layer 2 GMRP and the Layer 3 IGMP traffic from the host. The switch uses the
