I'm setting up a new router that has both an ADSL/PPPoE and a cable modem upstream. I've configured mpd5 for the PPPoE connection, and I'd like to have the cable modem provide a second, independent connection through FIB 1 over igb2.
rc.conf (partially):
ifconfig_igb2_descr="Cable Modem"
ifconfig_igb2="DHCP fib 1"
ifconfig_igb2_ipv6="inet6 accept_rtadv defaultif"
gateway_enable="YES"
ipv6_gateway_enable="YES"
pf_enable="YES"
dhclient_flags="-b"
dhcp6c_enable="YES"
dhcp6c_interfaces="igb2"
dhcp6c_fib=1
I think this should be sufficient to receive both an IPv4 and IPv6 address and
a default route, however, neither one is added. When I manually add them, they
are removed after a while.
$ ifconfig igb2
igb2: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

For IPv6, I thought that setting defaultif would make the kernel add the
default route when an appropriate RA is received, and on my old router, that
was working; I can't seem to see what difference I have in the config, apart
from using FIB 1 instead of the default.
And for IPv4, I see that I get the default router through DHCP, but somehow
/sbin/dhclient-script is not adding a default route. If I add it manually, it
will be removed eventually.
Any suggestions?
