You should place a # in front of the two lines:

> ifconfig_rl0 = "DHCP"
> ifconfig_re0 = "DHCP"

Next, you probably shouldn't place spaces before and after the equal 
signs.

See 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-ipv6.html.

You probably should create a ULA prefix or two, and assign these to 
your router interfaces. http://www.sixxs.net/tools/grh/ula/ might help 
you.

Something along these lines might help you achieve what you want:

ifconfig_rl0_ipv6="inet6 fd8f:d6d0:e6e7:100::1 prefixlen 64"
ifconfig_re0_ipv6="inet6 fd44:13de:a366:200::1 prefixlen 64"
ipv6_gateway_enable="YES"

Finally you probably should configure and enable Router Advertisement 
and Host Auto Configuration as explained in section 32.11.6 of 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-ipv6.html.
