TO_IN—The filtering mode has changed from Exclude to Include.
TO_EX—The filtering mode has changed from Include to Exclude.
ALLOW—The Source Address fields contain a list of additional sources from which the receiver
wants to obtain data. If the current filtering mode is Include, these sources are added to the
INCLUDE source address list. If the current filtering mode is Exclude, these sources are deleted
from the EXCLUDE source address list.
BLOCK—The Source Address fields contain a list of the sources from which the receiver no
longer wants to obtain data. If the current filtering mode is Include, these sources are deleted
from the INCLUDE source address list. If the current filtering mode is Exclude, these sources are
added to the EXCLUDE source address list.

IGMP support for VPNs

IGMP maintains group memberships on a per-interface base. After receiving an IGMP message on an
interface, IGMP processes the packet within the VPN to which the interface belongs. IGMP only
communicates with other multicast protocols within the same VPN instance.

Configuring basic IGMP functions

Before you configure basic IGMP functions, complete the following tasks:
• Configure any unicast routing protocol so that all devices are interoperable at the network layer.
Configure PIM.
•
• Determine the IGMP version.
Determine the multicast group and multicast source addresses for static group member
•
configuration.
Determine the ACL for multicast group filtering.
