Looking to tunnel between two routers however i cannot use IP addresses at all for either source or destination. Currently i have the source set to fa0/1 to combat this however i cannot set the destination ip at all. this also occurs with hostnames in destination. Using 1841 and the advanced IP ios version
Router>enable
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#ipv6 unicast-routing
Router(config)#interface tunnel 0
Router(config-if)#
%LINK-5-CHANGED: Interface Tunnel0, changed state to up
Router(config-if)#ipv6 address 2002::10/64 eui-64
Router(config-if)#ipv6 enable
Router(config-if)#tunnel source FastEthernet0/1
Router(config-if)#tunnel destination 2001::20
^
% Invalid input detected at '^' marker.

Should work I just tested it on one of my routers that's the way its enabled ,Your software definitely supports ipv6 under GRE , does it show an option for ipv6 when checking , tunnel destination ? with help
xxxxxxxxxxx(config-if)#tunnel destination ?
Hostname or A.B.C.D ip address or host name
X:X:X:X::X IPv6 address
dynamic destination dynamic
!
interface Tunnel212
no ip address
ipv6 enable
tunnel destination 2001:DB8:85A3::8A2E:370:7334
end
Tried your address too and it worked
interface Tunnel212
no ip address
ipv6 enable
tunnel destination 2001::20
end
FROM dOC
The following example shows how to configure a GRE tunnel over an IPv6 transport. In this example, Ethernet0/0 has an IPv6 address, and this is the source address used by the tunnel interface. The destination IPv6 address of the tunnel is specified directly. In this example, the tunnel carries both IPv4 and IS-IS traffic.
interface Tunnel0 ip address 10.1.1.1 255.255.255.0 ip router isis tunnel source Ethernet0/0 tunnel destination 2001:DB8:1111:2222::1 tunnel mode gre ipv6 ! interface Ethernet0/0 no ip address ipv6 address 2001:DB8:1111:1111::1/64 ! router isis net 49.0001.0000.0000.000a.00

I am not using gre. I am using VTI as outline in this document: Here
