Configuring a Static Multicast Route

Configuring a Static Multicast Route
When using PIM, the FWSM expects to receive packets on the same interface where it sends unicast
packets back to the source. In some cases, such as bypassing a route that does not support multicast
routing, you may want unicast packets to take one path and multicast packets to take another.
Static multicast routes are not advertised or redistributed.
To configure a static multicast route for PIM, enter the following command:
hostname(config)# mroute src_ip src_mask (input_if_name | rpf_neighbor} [distance]
For example:
hostname(config)# mroute 10.1.1.1 255.255.255.255 192.168.1.2
where 10.1.1.1 is the server that is sending out the multicast traffic, and 192.168.1.2 is the RPF neighbor
for FWSM.
You can specify the interface or the RPF neighbor, but not at the same time.
Note
To configure a static multicast route for a stub area, enter the following command:
hostname(config)# mroute src_ip src_mask input_if_name [dense output_if_name] [distance]
The dense output_if_name keyword and argument pair is only supported for Stub Multicast Routing.
Note

Configuring PIM Features

Routers use PIM to maintain forwarding tables for forwarding multicast diagrams. When you enable
multicast routing on the FWSM, PIM and IGMP are automatically enabled on all interfaces.
PIM is not supported with PAT. The PIM protocol does not use ports and PAT only works with protocols
Note
that use ports.

Disabling PIM on an Interface

You can disable PIM on specific interfaces. To disable PIM on an interface, enter the following
