Now I added ipv6 config to another server on same network. It's 
8.1-RELEASE amd64. Exactly same problem, but ping6 between these server 
works fine:
backup% ping6 2001:14b8:10:402:1::1
PING6(56=40+8+8 bytes) 2001:14b8:10:402:2::1 --> 2001:14b8:10:402:1::1
16 bytes from 2001:14b8:10:402:1::1, icmp_seq=0 hlim=64 time=0.356 ms
16 bytes from 2001:14b8:10:402:1::1, icmp_seq=1 hlim=64 time=0.163 ms

traceroute6 doesn't:
backup% traceroute6 2001:14b8:10:402:1::1
traceroute6 to 2001:14b8:10:402:1::1 (2001:14b8:10:402:1::1) from 
2001:14b8:10:402:2::1, 64 hops max, 12 byte packets
