A VPRN service is configured with BGP used as the CE-PE routing protocol.

VPN-IPv4 address families are required in order for routes to be exchanged with the PE.

Only default IPv4 address families are required since the CE is not aware of the VPRN service

Either IPv4 or VPN-IPv4 address families can be configured on the PE-CE BGP session

An IPv4 address family configuration is required for the PE-PE configuration.
