Hello, we are having an issue with ipv6 BGP peering. Our /64 range is not being advertised.
Config is as follows:
set protocols bgp 33XXX neighbor 2001:X:X:XX::XX:X address-family ipv6-unicast route-map export 'COGENT-OUT-IPV6'
set protocols bgp 33XXX neighbor 2001:X:X:XX::XX:X address-family ipv6-unicast route-map import 'COGENT-IN-IPV6'

set protocols bgp 33XXX neighbor 2001:X:X:XX::XX:X update-source '2001:X:X:XX::XX:Y'
