Cisco tunnel config

[Vitaly Chipitsyn]

Hello, everyone.

It is me (with my cisco) again. ;)
I have found IOS 11.3/IPv6 for Series 2501, and my present problem is
that I cannot find a proper way to configure tunnel to our
pTLA. Those of you who use ciscos, could you send me any hints? 

Sections of your `show running-config` as examples will be very helpful.

There is a command 'show ipv6 tunnel', but there is no command (none
that I could find) under configure-mode that I can use to actually
_configure_ a tunnel.

Generally, is there any documentation available that covers IPv6 part
of Cisco's IOS? I will look for it at www.cisco.com as a CCO-member,
so I am basicly asking about documentation other than from Cisco.

Thanks.
