RD - Route Distinguisher

A BGP speaker can only advertise one route per IP prefix and can therefore completely omit a route to a VPN if its addressing overlaps a different VPN, creating a one or the other scenario. The solution to this problem is to add an 8-byte RD (Route Distinguisher) to the IPv4 address, creating a unique 12byte VPN-IPv4 address.
