Enabling the GMRP Forward-All Option on a Switch Port

When you enable the GMRP forward-all option on a port, a copy of all multicast traffic that is registered
on the switch is forwarded to that port. Enable the forward-all option on any port that is connected to a
router that needs to receive any multicasts (routers do not support GMRP and cannot send GMRP join
messages). The forward-all option can also be used to forward all registered multicast traffic to a port
with a network analyzer or probe attached.
To enable the GMRP forward-all option on a switch port, perform this task in privileged mode:
