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.
