PIM-DM operating rules

The routing switch supports 2046 multicast flows in hardware. See,Flow capacity.

The multicast routing table (MRT) that PIM-DM creates allows up to 128 outbound VLANs at any given time. PIM-DM supports multicast routing across 128 VLANs (16 for the 2930F switch).

The routing switch allows one instance of PIM per VLAN. For networks using multinetted VLANs, all routers on the intended VLAN must have at least one common subnet if you intend on routing multicast packets. The routing switch provides a command for specifying which IP address PIM will use on each VLAN.

For the 2930F switch, the maximum number of routes is limited to 200.
