Usage guidelines
Local routers can exchange MDT information with their peers or peer groups only after you complete the
following tasks:
1. Create a BGP IPv4 MDT address family and enter its view.
2. Use the peer enable command to enable BGP to exchange routing information for an address
family with peers or peer groups.
The MDT information includes the IP address of the PE and default-group to which the PE belongs. On a
public network running PIM-SSM, the multicast VPN establishes a default-MDT rooted at the PE (multicast
source) based on the MDT information.
The configuration made in the BGP IPv4 MDT address family view takes effect only on BGP MDT
messages and BGP MDT peers or peer groups.
Examples
