Configuring and Customizing IGMP
117355-D Rev 00
3-35
In Figure 3-2, multicast traffic is forwarded from a nonmulticast network to a
nonmulticast interface on the router and is sent out through multicast interfaces on
the same router. To create an IGMP static forwarding policy for this type of
scenario:
Set the forwarding mode to “static to dynamic.”
Specify the in circuit (in this example, IGMP interface 1).
Set the inbound IGMP circuit’s static forward cache lifetime to a value
appropriate for the multicast protocol that will be transferring the traffic out of
the router. For instructions, see “Specifying the Static Forward Cache
Lifetime” on page 3-27.
