GRE/IPv4 Tunnel:
interface Tunnel0
no ip address
ipv6 address 2001:0DB8:1111:2222::1/64
tunnel source Ethernet0/0
tunnel destination 10.0.0.2
tunnel mode gre ip
GRE/IPv6 Tunnel:
interface Tunnel0
ip address 10.1.1.1 255.255.255.0
tunnel source Ethernet0/0
tunnel destination 2001:DB8:1111:2222::1
tunnel mode gre ipv6
!
interface Ethernet0/0
no ip addres
ipv6 address 2001:DB8:1111:1111::1/64
There quite a few examples!

Subject: GRE Tunneling for ipv6
Hi GS,
In Cisco Press Self-Study Implementing IPv6 Network book, there's a scenario
deploying ipv6 over gre tunnel.
Cisco uses the following configuration:
RouterR1#configure terminal
RouterR1(config)#int tunnel0
RouterR1(config-if)#ipv6 address 3ffe:b00:ffff:2::1/64
RouterR1(config-if)#tunnel source 206.123.31.200
RouterR1(config-if)#tunnel destination 132.214.1.10
RouterR1(config-if)#tunnel mode gre ipv6
RouterR2(config-if)#exit
I think command "tunnel mode gre ipv6" is used when tunneling is created
over ipv6 network
If so the correct configuration should be:
1. change tunnel source and destination addresses to ipv6 address
or
2. change mode to "tunnel mode gre" (this is default on int tunnel)
Am I correct?
Thanks
Phuc
