Configuring Access Node Control Protocol for IGMP

By using ANCP, IGMP is no longer terminated or proxied at the access node. Instead,
IGMP passes through the access node transparently. B-RAS terminates both the data
PVC and IGMP. After possible user permission verification, B-RAS may instruct the
access node, by using GSMP, to establish a multicast branch for the subscriber port.
Access Node Control Protocol (ANCP), also known as Layer 2 Control (L2C) works
with a special IGMP session to collect OIF mapping events in a scalable manner. For
additional information about configuring ANCP for IGMP, see Configuring ANCP in
the JUNOSe IP Services Configuration Guide.
For additional information about OIF mapping, see "Configuring Group Outgoing
Interface Mapping" on page 53 .

Configuring SSM Mapping

Source-specific multicast (SSM) mapping enables the router to determine one or
more source addresses for group G. The mapping effectively translates IGMPv1 or

Configuring Access Node Control Protocol for IGMP

Use the no version to remove the outgoing interface map association from the
interface.
See ip igmp apply-oif-map.
Use to create an OIF map.
Example
host1(config)#ip igmp oif-map OIFMAP atm 3/0.1 232.0.0.1/32 51.0.0.1/32
host1(config)#ip igmp oif-map OIFMAP atm 3/0.2 232.0.0.1/32 51.0.0.2/32
host1(config)#ip igmp oif-map OIFMAP atm 3/0.3 233.0.0.1/32
host1(config)#ip igmp oif-map OIFMAP atm 3/0.4 233.0.0.0/24 51.0.0.1/32
host1(config)#ip igmp oif-map OIFMAP atm 3/0.5 233.0.0.0/24 51.0.0.2/32
host1(config)#ip igmp oif-map OIFMAP self 0.0.0.0/0 51.0.0.0/24
Use the no version to remove an outgoing interface map attribute.
See ip igmp apply-oif-map.
Use to set the IGMP version (1, 2, or 3) for the interface or specify a passive
interface with only multicast-data-forwarding capability (passive).
Example
host1:dallas(config-if)#ip igmp version passive
Use the no version to set the version to the default, IGMPv2.
See ip igmp version.
