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.
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 .
Source-specific multicast (SSM) mapping enables the router to determine one or more
source addresses for group G. The mapping effectively translates IGMPv1 or IGMPv2
membership reports to an IGMPv3 report, enabling the router to continue as if it had
initially received an IGMPv3 report. After the router is joined to these groups, it sends out
PIM join messages and continues to enable joining from these groups, as long as it
continues to receive IGMPv1 and IGMPv2 membership reports and no change occurs to
the SSM mapping for the group.
When you statically configure SSM mapping, the router can discover source addresses
from a statically configured table.
