GMRP Commands

The GARP Multicast Registration Protocol provides a mechanism that allows 

networking devices to dynamically register (and de-register) Group 

membership information with the MAC networking devices attached to the 

same segment, and for that information to be disseminated across all 

networking devices in the bridged LAN that support Extended Filtering 

Services.  The operation of GMRP relies upon the services provided by the 

Generic Attribute Registration Protocol (GARP). GMRP is supported as 

described below.
The information registered, de-registered and disseminated via GMRP is in 

the following forms:

1 Group Membership information: This indicates that there exists one or 

more GMRP participants which are members of a particular Group, and 

carry the group MAC addresses associated with the Group. 

2 Group service requirements information: This indicates that one or more 

GMRP participants require Forward all Groups or Forward Unregistered to 

be the default filtering behavior. 

  NOTE: The Group Service capability is not supported.

Registration of group membership information allow networking devices to 

be made aware that frames destined for that group MAC address concerned 

should be forwarded in the direction of registered members of the group.  

Forwarding of frames destined for that group MAC address occur on ports on 

which such membership registration has been received.
Registration of group services requirement information allow networking 

devices to be made aware that any of their ports that can forward frames in 

the direction from which the group service requirement information has been 

received should modify their default group behavior in accordance with the 

group service requirement expressed. 

  NOTE: The Group Service capability is not supported.
