Routing metric in DHCP.

[Eric L. Chen]

Hi
Does any one knows how to set routing metric in DHCP interface?
My laptop has one ethernet and one wireless. Both of them are not always
connected.
In office, ethernet and wireless both connected. Or only wireless
connected if I moved to meeting room.
In home, only wireless is connected.
When both ethernet and wireless are connected, the default gateway
changes its Netif frequently. Both ath0 and bfe0 run DHCP client.
Can I add routing metric in DHCP interface?
My Settings:
~> cat /etc/rc.conf
ifconfig_bfe0="DHCP"
ifconfig_ath0="wme burst WPA DHCP"
...

~> netstat -rn -f inet
Routing tables
Internet:
Destination  Gateway      Flags Refs      Use  Netif Expire
default      10.8.0.254   UGS      0    95112   ath0
...
===== Later =====
