IP Multicast Routing
To display the IGMP snooping static groups, use the following command:
show igmp snooping vlan <name> static [group | router]
IGMP Snooping Filters
IGMP snooping filters allow you to configure a policy file on a port to allow or deny IGMP report and
leave packets coming into the port. (For details on creating policy files, see “Management Access
Security” on page 167.)
For the policies used as IGMP snooping filters, all the entries should be IP address type entries, and the
IP address of each entry must be in the class-D multicast address space but should not be in the
multicast control subnet range (224.0.0.x/24). After you create a policy file, use the following command
to associate the policy file and filter a set of ports:
configure igmp snooping vlan <vlanname> ports <portlist> filter [<policy> | none]
To remove the filter, use the none option.
To display the IGMP snooping filters, use the following command:
show igmp snooping {vlan} <name> filter
Configuring IP Multicasting Routing
To configure IP multicast routing:
1 Configure the system for IP unicast routing.
2 Enable multicast routing on the interface using the following command:
enable ipmcforwarding {vlan <name>}
3 Enable PIM on all IP multicast routing interfaces using the following command:
configure pim add vlan [<vlan_name> | all] {dense | sparse}
4 Enable PIM on the router using the following command:
enable pim
Configuration Examples
Figure 55 and Figure 56 are used in Chapter 16 to describe the Open Shortest Path First (OSPF)
configuration on a switch. See Chapter 16 for more information about configuring OSPF.
PIM-DM Configuration Example
In Figure 55, the system labeled IR 1 is configured for IP multicast routing, using PIM-DM.
