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.

The present disclosure is directed to adaptive networking policy with user defined fields and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more components to perform operations including generating a user defined attribute (UDA) value corresponding to a set of attributes; receiving, at a network device, a packet having one or more packet conditions; determining that the one or more packet conditions of the packet match the set of attributes of the UDA value; assigning a UDA tag to the packet, wherein the UDA tag corresponds to the UDA value and is configured for chaining with one or more other UDA tags; and taking an action on the packet based on the UDA tag.

A method for re-querying for routing information is disclosed. The method transmits an initial admission query to a gatekeeper or a request for routing information and receives an admission confirmation or routing information response with a destination address. The method then tries to establish a connection with the destination address. Upon reception of a call failure message including a failure cause, the method, optionally, increments a counter and transmits a re-query to the gatekeeper or other routing entity, and the re-query includes the failure cause and, optionally, a value of the query counter.
