7.20 Configuring Local MT

By configuring local MT, you can enable multicast packets to be forwarded through TE tunnels
on IS-IS networks.
7.20.1 Before You Start
Before configuring IS-IS local MT, familiarize yourself with the usage scenario, complete the
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
If multicast and an MPLS TE tunnel are deployed in a network, multicast packets may be
forwarded through the TE tunnel. As a result, the routers spanned by the TE tunnel cannot detect
the transmission of multicast packets, and therefore the routers cannot create any multicast
forwarding entry. You can configure local MT function and enable IGP Shortcut on the TE
tunnel to avoid the preceding problem. In this manner, a correct MIGP routing table can be
created to guide the forwarding of multicast packets.
Pre-configuration Tasks
Before configuring IS-IS local MT, complete the following tasks:

NOTE
Local MT can be configured only in the IS-IS process of the public network instance. In this case,
Forwarding Advertise cannot be configured.
