ASR-9000: config tunnel IPv6 over IPv4

Hi these.

I configurated tunnel IPv6 over IPv4. Althought interface tunnel is up.

But on SW_AGG_01, only ping successful: 1001:1:1::1, not ping 1001:1:1::2.

The same on SW_AGG_02, only ping successful: 1001:1:1::2, not ping 1001:1:1::1.

I don't know cause of problem.

Can everyone help me ????

Thanks.

interface tunnel-ip100

IPv6 over IPv4 GRE is not yet supported on the ASR 9000.

I believe that it is planned but not yet anounced what release it will be provided in.

Hi David,

 do we have support now?
