Predefined user roles

Usage guidelines
Execute this command before you use the peer enable command to enable BGP peers to exchange MDT information. MDT information includes the IP address of a PE device and the default-group to which the PE device belongs. On a public network running PIM-SSM, multicast VPN establishes a default-MDT rooted at the PE device (multicast source) based on the MDT information.
Configurations in BGP IPv4 MDT address family view take effect only on BGP MDT messages, BGP MDT peers, and BGP MDT peer groups.
Examples
# In BGP instance view of BGP instance default, create a BGP IPv4 MDT address family and enter its view.
<Sysname> system-view [Sysname] bgp 100 [Sysname-bgp-default] address-family ipv4 mdt [Sysname-bgp-default-mdt]
# In BGP instance view of BGP instance abc, create a BGP IPv4 MDT address family and enter its view.
<Sysname> system-view [Sysname] bgp 100 instance abc [Sysname-bgp-abc] address-family ipv4 mdt [Sysname-bgp-abc-mdt]
