GMRP Configuration
Chapter 14. GMRP Configuration
14.1 Brief Introduction to GMRP
GMRP (GARP Multicast Registration Protocol) is a kind of application of GARP (Generic
Attribute Registration Protocol), which is based on GARP working mechanism to maintain the
dynamic multicast register information in switch. All switches supported GMRP can receive
multicast register information from other switches and upgrade local multicast register
information dynamically and transfer it to other switches to make the consistency of multicast
information of devices supported GMRP in the same switching network. Multicast register
information transferred by GMRP includes local manual configuration of static multicast
register information and the dynamic multicast register information of other switch
14.2 GMRP Configuration
14.2.1 Enabling GMRP
Enable GMRP needs in both globally and port configuration. By default, GMRP disable in
both globally and port configuration.

14.2.2 Add Requisite Static Route Forwarded by
GMRP
It forwards dynamically broadcast learning from GMRP when startup GMRP, but it is
necessary for administrator to configure manually when GMRP forwards local static
broadcast.
