Configuring Logical Tunnel Interfaces on page 136
You can configure an ACX Series router to receive multicast traffic in a VRF domain. In
an IPTV solution, IPTV sources and receivers can be spread across different end points
of a network in a VRF domain. To receive the multicast traffic at the receiver's side, it is
necessary for the multicast traffic to be tunneled across the network to reach the end
receiving device or the subscriber. This tunneling is usually done using the Multicast Virtual
Private Network (MVPN) technology.
ACX Series routers do not support MVPN technology. An alternate method for receiving
the multicast traffic in the VRF domain in ACX Series router is by associating a global
logical interface to a logical interface in the VRF domain. The global logical interface acts
as a proxy for receiving the multicast traffic on the logical interface in the VRF domain.
To associate a global logical interface to a logical interface in the VRF domain, you need
to configure an IRB interface in a global domain to act as a proxy for the logical interface
in the VRF domain.

Domain on page 141
Limitations on page 141
To configure a proxy logical interface in the global domain, you need to create logical
tunnel (lt-) interface and IRB interface and then associate the IRB interface to a bridge
domain. The following is a example to configure a proxy logical interface in the global
domain:
Create an logical tunnel (lt-) interface.
