Used to configure ports as router ports.
config router_ports <vlan_name 32> [add | delete] <portlist>

connected to multicast-enabled routers. This will ensure that all
packets with such a router as its destination will reach the multicast-
enabled router − regardless of protocol, etc.
<vlan_name 32> − The name of the VLAN on which the router port
resides.
<portlist> − Specifies a port or range of ports that will be configured
as router ports.
Only administrator-level users can issue this command.
