IPv4-IPv6 Transition/Coexistence• A wide range of techniques have been identifiedand implemented, basically falling into threecategories:1. Dual-stack techniques, to allow IPv4 and IPv6 toco-exist in the same devices and networks2. Tunneling techniques, to avoid order dependencieswhen upgrading hosts, routers, or regions3. Translation techniques, to allow IPv6-only devices tocommunicate with IPv4-only devices• Expect all of these to be used, in combinationRST-130012394_04_2006_c2© 2006 Cisco Systems, Inc.
