Clearing IGMP statistics

To clear statistics for IGMP traffic, enter the following command.
BigIron RX# clear igmp traffic
Syntax: clear igmp traffic
This command clears all the multicast traffic information on all interfaces on the device.

IGMP V3 and source specific multicast protocols

When IGMP V3 and PIM Sparse (PIM-SM) is enabled, the source specific multicast service (SSM)
becomes available. SSM simplifies PIM-SM by eliminating the RP and all protocols related to the
RP.
Configuring a static multicast route
Static multicast routes allow you to control the network path used by multicast traffic. Static
multicast routes are especially useful when the unicast and multicast topologies of a network are
different. You can avoid the need to make the topologies similar by instead configuring static
multicast routes.
NOTE
This feature is not supported for DVMRP.
You can configure more than one static multicast route. The always uses the most specific route
that matches a multicast source address. Thus, if you want to configure a multicast static route for
a specific multicast source and also configure another multicast static route for all other sources,
you can configure two static routes as shown in the examples below.
To add static routes to multicast router A (refer to
following.
PIMRouterA(config)# ip mroute 207.95.10.0 255.255.255.0 interface ethernet 2/3
distance 1
PIMRouterA(config)# ip mroute 0.0.0.0 0.0.0.0 interface ethernet 2/3 distance 1
PIMRouterA(config)# write memory
Syntax: ip mroute <ip-addr> interface ethernet <slot>/<portnum> | ve <num> [distance <num>]
Or
Syntax: ip mroute <ip-addr> rpf_address <rpf-num>
The <ip-addr> command specifies the PIM source for the route.
