[c-nsp] ipv6 vpn

[Luan Nguyen]

Hi all,
say that I have a traditional VPN running GRE/IPSEC transport mode and I
want to enable ipv6 on the lan sides of all the vpn nodes.
Could I just dual stack the lan with ipv6, advertise it throughout the vpn
and be happy?  Has anyone try this method before?  or do I have to change
the tunnel mode to ipv6, add another line to the crypto acl to have 41
additional to 47...etc?
eigrp doesn't support ipv6 does it?
 
TIA
