Enabling GMRP Forward-All Option

When you enable the GMRP forward-all option on a port, a copy of all multicast traffic registered on the
switch is forwarded to that port. We recommend enabling the forward-all option on any port connected
to a router. 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 forward a copy of all GMRP multicast packets registered on the switch to a port, perform this task in
privileged mode:
