Hi Umit,

it's good that you have debugs attached:

RP/0/RSP1/CPU0:Jun 19 21:17:13.671 : bgp[1039]: [ioct]: Open check failed for 192.168.96.4 - 'No gbl ipv6 addr'

You need an IPv6 address on the peering interface for "address-family ipv6 unicast" - otherwise the BGP session will not come up and stays idle, as open check fails

it is a known issue logged as CSCtq26829:

Regards,

Ivan.
