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. Enable the forward-all option on any port connected to a router that
needs to receive any multicasts (routers do not support GMRP and so cannot send GMRP join mesages).
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:
