Configuring the Action

Configure IGMP Filtering

1. Enable IGMP filtering on the switch.
2. Define an IGMP filter with IPv4 information.
3. Assign the IGMP filter to a port.

Static Multicast Router

1. For each Mrouter, configure a port, VLAN, and IGMP version of the multicast
router.
2. Verify the configuration.

Each IGMP filter can allow or deny IPv4 multicasts to the range of IPv4 addresses
configured. If you configure the filter to deny IPv4 multicasts, then IGMP
Membership Reports from multicast groups within the range are dropped. You can
configure a secondary filter to allow IPv4 multicasts to a small range of addresses
within a larger range that a primary filter is configured to deny. The two filters
work together to allow IPv4 multicasts to a small subset of addresses within the
larger range of addresses.
Note: Lower‐numbered filters take precedence over higher‐number filters. For
example, the action defined for IGMP filter 1 supersedes the action defined for
IGMP filter 2.

A static Mrouter can be configured for a particular port on a particular VLAN. A
static Mrouter does not have to be learned through IGMP Snooping. Any data port
can accept a static Mrouter.
When you configure a static Mrouter on a VLAN, it replaces any dynamic
Mrouters learned through IGMP Snooping.
To configure a static multicast router
RS G8264(config)# ip igmp mrouter 5 1 2
RS G8264(config)# show ip igmp mrouter
