What does the PE router convert the IPv4 prefix to within an MPLS VPN?
In an MPLS VPN, the PE (Provider Edge) router converts the IPv4 prefix into a VPN-IPv4 prefix by combining the IPv4 address with a 64-bit route distinguisher (RD). This VPN-IPv4 prefix uniquely identifies the customer address within the MPLS VPN, allowing for the use of overlapping IP address spaces by different customers.
Explanation The IP prefix is a member of the IPv4 address family. After the PE device learns the IP prefix, the PE converts it into a VPN-IPv4 prefix by combining it with an 8-byte route distinguisher (RD). The generated prefix is a member of the VPN-IPv4 address family. It uniquely identifies the customer address, even if the customer site is using globally nonunique (unregistered private) IP addresses.
