So, ifdown does succeed in taking the interface down. I wander why the routes
aren't getting removed?
Are we sure that's the case? I think what is happening is
that the routes are going down, but to bring up peth0
again, we only do a ip link set peth0 up, which creates
an interface route, but does not automatically generate
a default route (since we aren't transferring routes
in this case).
The netstat -rn should confirm that.
Could you do:
ifconfig
netstat -rn
ifdown eth0
netstat -rn
ifconfig
Thanks,
Ian
I am scratching my head on how the del_addr should
make a difference here, since the ifdown should have
taken down the routes..
There are several ways to clean up, if the above
is correct.
thanks,
Nivedita

ian,
as the discussion in this thread, service os netwok will
break after
xend start.
this simple patch can work on my mahine.
but strange error still occur in xend.log and xend start
takes more
time with ifdown/ifup.
I guess the patch can't do any harm, but why doesn't ifdown
remove the
routes?
Before starting xend, please can you post the output of the
following
sequence:
ifconfig
ifdown eth0
ifconfig
Thanks,
Ian
