IPv6 tcpdump at FreeBSD!!!

Hi,
Am working on FreeBSD7.4/i386 on IPv6 configuration..
I assigned Global IPv6 address..
Now am trying to dump IPv6 packets to another host which is an AIX machine..
I used "tcpdump -i bce0 -s 512 -vv ip6 or proto ipv6" where bce0 is the FreeBSD interface..
I get "tcpdump: listening on bce0, link-type EN10MB (Ethernet), capture size 512 bytes" as output!!
Can You please tell me how to sort out this issue and to make tcpdump possible!!!!
Expecting your reply soon...

do you have

Code:
device bpf

enabled in your kernel?

You can check this with:

Code:
strings /boot/kernel/kernel | grep bpf

if device bpf is not in the results, you need to compile it into the kernel.
