I am trying to set up IPsec in a IPv6 environment. However, when I configure "crypto map" I wasn't able to "set peer" to a IPv6 peer address. Why is that?

I used Virtual Tunnel Interface instead of Crypto Map and it worked. But I need to IPsec in transport mode instead of tunnel mode.

I think here is no support for mixed mode which is ipv6 traffic through ipv4 tunnel and vice versa in VTI . Better solution is Gre tunnel.
