Configuring Label Switched Multicast
Deployment of an LSM MLDP-based MVPN involves configuring a default MDT and one or more data
MDTs. A static default MDT is established for each multicast domain. The default MDT defines the path
used by PE routers to send multicast data and control messages to other PE routers in the multicast domain.
A default MDT is created in the core network using a single MP2MP LSP.
An LSP MLDP-based MVPN also supports dynamic creation of the data MDTs for high-bandwidth
transmission. For high-rate data sources, a data MDT is created using the P2MP LSPs to off-load the traffic
from the default MDT to avoid unnecessary waste of bandwidth to PEs that are not part of the stream. You
can configure MLDP MVPN for both the intranet or extranet. This configuration section covers the rosen
based MLDP profile. For configuration examples of other MLDP profiles, see

Purpose
commit—Saves the configuration changes, and remains
within the configuration session.
end—Prompts user to take one of these actions:
• Yes— Saves configuration changes and exits the
configuration session.
• No—Exits the configuration session without
committing the configuration changes.
• Cancel—Remains in the configuration mode, without
committing the configuration changes.
Displays all MDT data streams.
In this example, loopback 1 is the per-VRF MDT source.
