[j-nsp] IPv6 Outer header tunnels

[Brandon Bennett]

Does anyone know if JunOS supports IPv6 as the outer header for GRE or
IPinIP tunnels?

For example:
gr-0/0/0 {
    unit 1 {
        tunnel {
            source 2001:1234:4561::1;
            destination 2001:1234:4561::2;
        }
        family inet {
            address 10.1.10.2/30;
        }
    }
}

Or IPinIP based

ip-0/0/0 {
    unit 1 {
        tunnel {
            source 2001:1234:4561::1;
            destination 2001:1234:4561::2;
        }
        family inet {
            address 10.1.10.2/30;
        }
    }
}


I have tried this on a J-series and it doesn't seem to be supported.
[edit interfaces gr-0/0/0 unit 1 tunnel source]
'source 2001:1234:4561::1; '
invalid ip address or hostname: 2001:1234:4561::1

Is there a knob or switch I am missing?  This seems to be simple
functionality.
