ip-mroute − multicast routing cache management
ip mroute show [ [ to ] PREFIX ] [ from PREFIX ] [ iif DEVICE ] [ table TABLE_ID ]
mroute objects are multicast routing cache entries created by a user-level mrouting daemon (f.e. pimd or mrouted ).
Due to the limitations of the current interface to the multicast routing engine, it is impossible to change mroute objects administratively, so we can only display them. This limitation will be removed in the future.
show - list mroute cache entries
to PREFIX (default)
the prefix selecting the destination multicast addresses to list.
the interface on which multicast packets are received.
the prefix selecting the IP source addresses of the multicast route.
the table id selecting the multicast table. It can be local, main, default, all or a number.
