IPv6 - traceroute6 not working

[Marcelo Gondim]

Hi all,

I have IPv6 deployed here in ISP and everything works normally. Today I 
was testing a traceroute and it did not work. Below an example:

(root at rt01)[~]# ping6 ipv6.google.com
PING6(56=40+8+8 bytes) 2001:xxxx:2001:1001::96 --> 2800:3f0:4001:813::1004
16 bytes from 2800:3f0:4001:813::1004, icmp_seq=0 hlim=60 time=6.449 ms
16 bytes from 2800:3f0:4001:813::1004, icmp_seq=1 hlim=60 time=6.266 ms
16 bytes from 2800:3f0:4001:813::1004, icmp_seq=2 hlim=60 time=6.340 ms
16 bytes from 2800:3f0:4001:813::1004, icmp_seq=3 hlim=60 time=6.410 ms
^C
--- ipv6.l.google.com ping6 statistics ---
4 packets transmitted, 4 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 6.266/6.366/6.449/0.070 ms

(root at rt01)[~]# traceroute6 ipv6.google.com
traceroute6 to ipv6.l.google.com (2800:3f0:4001:813::1004) from 
2001:xxxx:2001:1001::96, 64 hops max, 12 byte packets

(root at rt01)[~]# uname -a
FreeBSD rt01.xxxxx.com.br 10.1-RELEASE FreeBSD 10.1-RELEASE #2 r274375:

root at rt01.xxxxx.com.br:/usr/obj/usr/src/sys/GONDIM10  amd64

Must enable some sysctl or may be a bug?

Best regards,
