Hello,
we have a dot1q tunnel to our co-location
and can ping the servers in the co-location
over IPv4, but not over IPv6. The servers
get an IPv6 address through the dot1q tunnel
from the router interface per stateless
address autoconfiguration, but I can't reach
the servers over IPv6. Between the servers
on each site of the tunnel IPv6 is working.
I was thinking dot1q tunnel is layer 2 and
IPv4/IPv6 doesn't matter ?
Is there something special to configure for
IPv6 through a dot1q tunnel ?
Regards
Ralf

Hello,
turn on 'debug ipv6 packet', that looks like the best option (and post the output)...
