Thanks for the response.
I tried.
However, It did not resolve....
# ping6 -I eth1 2000:8000:12:6:192:168:11:8
PING 2000:8000:12:6:192:168:11:8(2000:8000:12:6:192:168:11:8) from
fe80::a00:27ff:fe03:5b8a eth1: 56 data bytes
First off, I assume you can ping your link-local address:
ping6 -I eth1 fe80::a00:27ff:fe03:5b8a
Second, you never mentioned how eth1 was assigned its IPv6 address.
Given that you've tried to embed an IPv4 address within an IPv6
address (which is normally done with a 0:0:0:0:0: prefix), I'd guess
you did it manually. If so, with what tools?
