Subject: PPP dynamic IP routing
Content-Type: text/plain; charset=us-ascii

I use a dial up phone to dial up to my ISP. Both my ISP and I got ip
addresses 
randomly. To do automatic routing, I use Ip style as follows in ppp.conf
and 
ppp.linkup.
    ifconfig 203.70.2.66/24 203.70.2.4/24 in ppp.conf
    add 0 0 203.70.2.4/24 in ppp.linkup
But it seems not much help. Now I still have to add default route
manually.
In linux I can solve this problem using device name.
Thanks.
