(usagi-users 02226) IPv4-in-IPv6

[Peter <usagi@xxxxxxxxxxxx>]

Hi,

is possible on LINUX with or without usagi kernel tunnelling ipv4 in ipv6 ?
So I mean if is possible something like this:

A.(4&6 router)--B.(4&6 router)--C.(4&6router)-->>D.INTERNET(IPv4)
	   native ipv6    native ipv4         
 	    (4in6)          (6in4)

so between B. and C. points I need tunneled IPv4-in-IPv6 ..the problem is
that I can't configure B. router so I can't use everywhere native 4&6 :(
Has anyone idea how co configure that?
Thanx for help.

	Peter
