6to4 Help

This is a scheme similar to that I’m using. A host in the left (ipv6) must communicate with the host in the right (ipv6 to) via an IPV4 Tunnel (router to router)

Hi, i need to set up a 6to4 tunnel and i dont know how to do.
Is there a tutorial? or a how to?

Thanx!

it’s not really any different than an ipip or l2tp tunnel. Just add the sit interface on both sides and point them at each other using their ipv4 addresses. Then assign a ipv6 routing subnet (/64 or /128 ?) on top of that interface to route things thru.

“Then assign a ipv6 routing subnet (/64 or /128 ?) on top of that interface to route things thru.”

I do not understand this part, what do u mean?
