Perhaps the ip-up / ip-down scripts of pppd could help you to
automatically do this load balancing script job?

I have been successfully implementing load balancing gateways for
multiple ISP links at various locations using Julian's patches and as
suggested in LARTC HowTo. At one location, one of the ISPs is
providing connectivity through a PPOE DSL link which has to be dialled
in everytime to connect. The gateway has been configured on a Fedora
Core 3 based system and I have recompiled the 2.6.12 kernel after
applying Julian's patches. I have configured the DSL modem in bridge
mode and connected it to an ethernet interface on the gateway and use
the DSL dialer in Fedora Core 3 to connect to the ISP. This creates a
ppp0 interface when the connection goes live which is alloted a static
Public IP. The dialer has been configured to redial as and when the
link goes down. However the problem is that the kernel is not able to
detect when this DSL interface (ppp0) comes back and does not restore
the gateway through this link. The loadbalancing script has to be run
again to make the kernel treat this gateway as LIVE and make the
traffic go out through it.
Has anyone encountered a similar problem ? I have never come across
such an issue wherever the link is terminating on an ethernet
interface. This ISP is insisting on dialling and then establishing the
a PPOE interface. Any suggestions ?
Thanks,
Manish
