How to ignore a default route for one of the dhclient-ed interface?

[Anton Yudin]

Hello.

  I'm running a FreeBSD 14 with two interfaces that use DHCP.
  I would like to make one of the interfaces to never set the default route.
  Right now the first interface to be fully up sets the default route.

  I tried to set the following in /etc/dhclient.conf
---------------8<------------------------
  interface "wan1" {
      ignore routers;
  }
---------------8<------------------------
  but the default route still gets set.

  I ended up creating a /etc/dhclient-enter-hooks with a very hacky code
that overrides the "route" command:
---------------8<------------------------
route() {
        if [ "X$interface" = "Xwan1" -a "X$2" = "Xdefault"  ]; then
                echo "ignore route $1 $2 $3 $4" | logger -t "enter-hooks"
        else
                /sbin/route $1 $2 $3 $4
        fi
}
---------------8<------------------------

Is there a better way of doing this?

Thanks.
