When used with no option, this command displays information for the complete IPv4 multicast routing table.
- group group
- Shows IPv4 multicast routes for the specified multicast group. The format is an IPv4 multicast address.
- source source
- Used in source-specific multicast. Shows multicast routes for the specified IPv4 multicast source. The format is an IPv4 multicast address.
- dense
- Shows dense-mode IPv4 multicast routes.
- sparse
- Shows sparse-mode IPv4 multicast routes.
- count
- Shows IPv4 multicast-route and packet-count information.
- summary
- Shows abbreviated IPv4 multicast route information.
Operational mode
