Abstract
In one embodiment, a method includes determining, by a router, a common prefix pool from a transport interface associated with a transport virtual private network (VPN). The method also includes identifying, by the router, a prefix associated with a service VPN and generating, by the router, an IPv6-to-IPv6 Network Address Translation (NAT66) prefix translation using the common prefix pool and the prefix. The NAT66 prefix translation includes a predetermined prefix length. The method further includes automatically installing, by the router, the NAT66 prefix translation into a translation table.
