Re: ipv6 tunnels and IGPs

All,

I've been looking into ipv6 tunnels lately. I noticed when doing a
manual tunnel with GRE or ipv6ip I am able to use IGPs across the tunnel
without any problems.

However, when I do ISATAP, 6to4, or ipv4 compatible ipv6tunnels my IGPs
don't work.

I noticed in the doccd and other documentation on 6to4 automatic tunnels
that they use static routes for the 2002:/16 and ::/0. And for ISATAP
for the ::/0. But, in the lab we usually cant use static routes so....

Has anyone been able to get IGPs to work thorough these tunnel modes?
Or am I doing something wrong?

Any input appreciated.

andy
