we always accept and forward ip packets to customers, for this we need to use ipv4 address-family.
When the customers packets are being received by PE (Provider Edge) they become labeled one and to forward labeled packets to different PE/RR; address-family vpnv4 is required.
In short we can say that ipv4 address-family is being used for customers and vpnv4 address-family is used by SP (Service Provider) core.
