When considering the IPv6 product, I would suggest you read USGv6-Revision-1 (1) to define the specification you need for the product. Then go to the USGv6 Registry (2), select the features and read the Supplier Declaration of Conformity (SDOC) to ensure that the product meets your requirements.

Speed of router depends on degree of parallelism. So, for quick routing table lookup, if you provide 128bit TCAM for IPv6 in addition to 32bit TCAM for IPv4, speed is mostly same, though, for each entry, TCAM for IPv6 costs 4 times more and consumes 4 times more power than that for IPv4.

Cisco and Juniper routers have had v6 functionality for over 10 years. Lucent/Nokia, and others. Check UNL list at https://www.iol.unh.edu/registry/usgv6 for v6 compliant routers and switches. John Lee On Fri, Nov 19, 2021 at 5:48 PM John Levine wrote: > It appears that Michael Thomas said: >
