The interface MTI 0 will automatically obtain an IP address after BGP peer
configuration on PE 3. This address is the loopback interface address specified in
the BGP peer configuration. The PIM mode running on MTI 0 is the same as the
PIM mode running on all the interfaces in VPN instance a.
The interface MTI 1 will automatically obtain an IP address after BGP peer
configuration on PE 3. This address is the loopback interface address specified in
the BGP peer configuration. The PIM mode running on MTI 1 is the same as the
PIM mode running on all the interfaces in VPN instance b.
# Bind Loopback 2 to VPN instance b, configure an IP address and enable PIM-SM
on the interface.
