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 that the interface belongs to. If IGMP that runs in a
VPN needs to exchange information with another multicast protocol, it passes the information only to the
protocol that runs in this VPN.
Protocols and standards

For the configuration tasks in this section:
• In IGMP view, the configuration is effective on all interfaces. In interface view, the configuration is
effective on only the current interface.
