Tunneling IPv6
I'm setting up a backup tunnel across the Internet to connect two sites and
want to dual-stack ipv4+ipv6.

I've built a GRE tunnel and configured IPv4 on it, works fine.

But, when adding ipv6 addr on GRE tunnel, I get:
"Error - IPv6 address can be configured ONLY on IPv6 tunnels"

Ok, so I'll try to add a separate IPv6 tunnel:

SSH@XMR(config)#int tunnel 2
SSH@XMR(config-tnif-2)#tunnel mode ipv6ip
SSH@XMR(config-tnif-2)# tunnel source x.y.z.38

SSH@XMR(config-tnif-2)# tunnel destination x.y.z.186
Error - Tunnel src and dest not unique, match that of Tunnel 1

Unfortunately I don't have extra IPv4 source and dest IPs that I can burn
up.

This is an XMR box running NI 5.5.

Cisco and Juniper both support IPv4+IPv6 on top of GRE, has Brocade
implemented this in a newer release?

I also tried to do IPv6 tunnel on top of IPv6, but that doesn't seem to be
available either. Is there something I've missed?
