Transitioning between communication protocols between networks

摘要

A method is provided in one particular example and may include obtaining routing information for a natively supported Internet protocol of a first network that uses a first routing policy; identifying a route with a tunnel endpoint using the routing information, where the tunnel endpoint supports transitioning between a plurality of Internet protocols; generating tunnel information for the route; and sending the route and the tunnel information to a network element in a second network that uses a second routing policy.

1. A method, comprising:
obtaining routing information for a plurality of Internet Protocol (IP) addresses in a first network that natively supports a first internet protocol; generating a first Border Gateway Protocol (BGP) update message comprising the routing information for the plurality of IP addresses in the first network and further comprising an additional IP address in the first network and an indication that the additional IP address in the first network is to be used as a tunnel endpoint within the first network for receiving data destined to any of the plurality of IP addresses in the first network; and sending the first BGP update message to a network element in a second network.
