Description of problem:
According to the ppp man page ppp runs /etc/ppp/ip-up with the following parameters:

$1=interface-name $2=tty-device $3=speed $4=local-IP-address
$5=remote-ip-address $6=ipparam

/etc/ppp/ip-up runs /etc/sysconfig/network-scripts/ifup-post with the
following parameters:

$1=ifcfg-${LOGDEVICE} where ${LOGDEVICE} is ipparam from above.

Here we just lost the details of the real interface-name that we need to add a
static route through a dynamically allocated ppp interface.
It can, however, be recovered from the files in /var/run/ppp-{ipparam}.pid that
was created by the ifup-ppp script, although it would be far better to pass it
straight through.

/etc/sysconfig/network-scripts/ifup-post runs
/etc/sysconfig/network-scripts/ifup-routes ${DEVICE} ${NAME} where ${DEVICE} is
${LOGDEVICE} above and ${NAME} is NAME as defined in the configuration file
ifcfg-ppp?

Adding
[ -f /var/run/ppp-$1.pid ] && {
  LOCALDEVICE="dev `tail -1 /var/run/ppp-$1.pid`"
}
near the top of /etc/sysconfig/network-scripts/ifup-routes and
changing all occurrances of /sbin/ip route add $line to
/sbin/ip route add $line $LOCALDEVICE will work around the problem
as long as the ipparam parameter remains set by ifup-ppp and is not
overridden by an entry in /etc/ppp/peers/ppp?

This is a wastefull solution, though.

Version-Release number of selected component (if applicable):
initscripts-7.14-1

How reproducible:
Always

Steps to Reproduce:
1. echo 10.1.2.0/24 > /etc/sysconfig/network-scripts/route-ppp4
2. ipup ppp4
3. interface comes up.


Actual Results:  1. Routing is not added.

    

Expected Results:  1. Routing should have been added through the newly brought
up ppp link.


Additional info:

1. It cannot work since ip route does not know where to route to.
2. I am using ppp-2.4.2-b1 and pptp-linux client, but that really shouldn't make
any difference since the behaviour of ppp in relation to the scripts is the same.
