You're tunneling IPv6 in IPv4, so the IPv4 will need a route between routers. Of course the FastEthernet interface works, it's directly connected.
Easiest option is static:
R1:
ip route 1.0.0.2 255.255.255.255 192.168.12.2
R2:
ip route 1.0.0.1 255....
You're thinking of "unique local" which can be used, although I've never seen it bothered with.
It's actually fc00::/7, so you'd use:
fc00::134:23:33:22
Although I'm not sure that's what you want.
Visually, that "maps" to the IPv4 address, but logica...
Since all link local addresses start with fe80::/64, it's impossible to route for a machine with multiple interfaces - they all will have the same route. The interface appended tells the operating system which interface to send the traffic out. Not...
Think of it this way:
How is 172.16.10.6 /30 in the 172.16.10.4 /30 subnet?
172.16.10.4 /30
172.16.10.5 /30
172.16.10.6 /30 <---
172.16.10.7 /30
You've done your subnetting in your question. The last nibble "6" is comprised of bits 60 - 63 in an I...
IPv6 addresses beginning with 2002::/16 are special '6to4' addresses (see: http://en.wikipedia.org/wiki/6to4).The 6to4 address is created by appending the hex version of the IPv4 address to the '6to4' prefix:In your example:2002:192.168.99.1::/64200...
