Configuring Transactional Multicast 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 any user permission verification, B-RAS may instruct the access
node (using GSMP) to establish a multicast branch for the subscriber port.
ANCP works with a special IGMP session to collect OIF mapping events in a scalable
manner. For additional information about configuring IGMP and about OIF mapping,
see Configuring IGMP in JUNOSe Multicast Routing Configuration Guide.

Creating an IGMP Session for ANCP

Use the l2c ip oif command to create an IGMP session for ANCP. This session enables
ANCP to listen to OIF mappings and, in turn, convey cross connect events to the
appropriate ANCP neighbor (access node).
l2c ip oif
Use to configure a QoS adjustment factor that is applied to the upstream data
rate and downstream data rate reported by ANCP for a DSL type. The adjustment
factor is used to generate an accurate QoS shaping rate.
The factor is applied for all subscribers that use the specified DSL line type
Example
host1(config-l2c)#adjustment-factor adsl1 45
host1(config-l2c)#adjustment-factor adsl2 55
host1(config-l2c)#adjustment-factor adsl2+ 67
host1(config-l2c)#adjustment-factor vdsl 91
host1(config-l2c)#adjustment-factor vdsl2 55
host1(config-l2c)#adjustment-factor sds 12
Use the no version to restore the default condition, wherein no adjustment factor
is applied to the ANCP-reported value. This command has the same effect as
applying an adjustment factor of 100 to a DSL line type.
See adjustment-factor.
Use to create an IGMP session at the virtual router within the context.
Example
host1(config)#l2c ip oif
Use the no version to remove the IGMP session.
See l2c ip oif.
