Specifying the MD source interface
An MTI of a VPN instance uses the IP address of the MD source interface as the source address to
encapsulate multicast packets for the VPN instance.
Configuration restrictions and guidelines
When you specify the MD source interface, follow these restrictions and guidelines:
•
Perform this task on PE devices.
•
For the PE device to obtain correct routing information, you must specify the interface used for
establishing BGP peer relationship as the MD source interface.
•
For an MD that transmits both IPv4 and IPv6 multicast packets, you must specify the same MD
source interface in MD IPv4 and IPv6 address family views.
Configuration procedure
To specify the MD source interface:
Step
1.
Enter system view.

Enter MD view.
3.
Enter MD address family
view.
4.
Specify the MD source
interface.
Configuring MDT switchover parameters
To decrease traffic interruption caused by frequent default-MDT to data-MDT switchovers, you can
specify a data-delay period. The switchover occurs a data-delay period after the multicast VPN data
first arrives, regardless of whether multicast VPN data keeps arriving during the period.
Configuration restrictions and guidelines
When you configure MDT switchover parameters, follow these restrictions and guidelines:
