Configuring MD VPN

This section describes how to configure MD VPN.

Configuration prerequisites

Before you configure MD VPN, complete the following tasks:
•
Configure a unicast routing protocol on the public network.
•
Configure MPLS L3VPN on the public network.
•
Configure PIM-DM, PIM-SM, BIDIR-PIM, or PIM-SSM on the public network.
•
Determine the VPN instance names and RDs.
•
Determine the default-groups.
•
Determine the source address for establishing BGP peers.
•
Determine the data-group range and the MDT switchover criteria.
•
Determine the data-delay period.
•
Determine the data-holddown period.

Enabling IP multicast routing for a VPN instance

Before you configure any MD VPN functionality for a VPN instance, you must create a VPN instance
and enable IP multicast routing for the VPN instance.
Perform this task on PE devices.
To enable IP multicast routing for a VPN instance:
Step
1. Enter system view.
2. Create a VPN instance and
enter its view.
3. Configure an RD for the VPN
instance.
4. Return to system view.
5. Enable IP multicast routing
for the VPN instance and
enter MRIB view of the VPN
instance.

•
Enable IPv4 multicast routing
and enter MRIB view of the
VPN instance:
multicast routing

name
•
Enable IPv6 multicast routing
and enter IPv6 MRIB view of
the VPN instance:
ipv6 multicast routing
vpn-instance vpn-instance-
name

Remarks
N/A
By default, no VPN instances
exist.

command, see MPLS Command
Reference.
By default, a VPN instance is not
configured with an RD.

command, see MPLS Command
Reference.
N/A
By default, IP multicast routing is
disabled in a VPN instance.
