With IPv6 growing, if we were to design a native IPv6 router, with IPv4 functionality thrown in, then is it possible to design a more optimal IPv6 router, than what exists today? OK, I'll bite.  What would qualify as a native IPv6 router?  Is this another concept as silly as hardware vs

Optimal IPv6 router

2012-02-05 Thread Glen Kent
Hi, Most routers today are basically IPv4 routers, with IPv6 thrown in. They are however designed keeping IPv4 in mind. With IPv6 growing, if we were to design a native IPv6 router, with IPv4 functionality thrown in, then is it possible to design a more optimal IPv6 router, than what exists

optimal IPv6 router, than what exists today? Asic based forwarding engines with ipv6 support are more than a decade old at this point. If one looks at an asr9000 or an MX or T that looks like an ipv6 router to me. Glen
