[LARTC] Flushing Dead Links

[mok2]

hi, I am trying to maintain a connection to the internet through my modem and a connection through network.
I route most my traffic through the modem and only select traffice through the fast connection.. handy for 
controlling users that want full access to the net :)

i run from my ppp startup a script that adds in this as my gateway

default  proto static 
        nexthop via 260.74.283.1  dev eth0 weight 1
        nexthop via 5.4.48.10  dev ppp0 weight 11

it works fine but when the connection drops it puts the ppp0 gw as a deadlink and when it redials it 
still sees it as a dead link the only way i can make it work again is to reboot.. 
how can i flush this dead link ?

When ppp0 drops
default  proto static 
        nexthop via 250.74.283.1  dev eth0 weight 1
        nexthop via 5.4.48.10  dev if40 weight 11 dead

When it redials again
default  proto static 
        nexthop via 260.74.283.1  dev eth0 weight 1
        nexthop via 5.4.48.10  dev if40 weight 11 dead

-regards mok2

	You can try to recreate the route. The routes remember the
device by index, not by name and can not detect that the new
device is a replacement for the previous one. The ifXXX name means
the device is unregistered which is bad. Routes containing
unregistered devices should be recreated.

How do i recreate the route ? i re-run this script everytime the connection goes up but it
only works the first time, when it redials it doesnt work anymore

ip rule add prio 201 from $eth0_network/24 table 201
ip route add default via $eth0gw dev eth0 src $ethoSRC proto static table 201
ip route append prohibit default table 201 metric 1 proto static

ip rule add prio 202 from $pppgw/32 table 202
ip route add default via $pppgw dev ppp0 src $pppSRC proto static table 202
ip route append prohibit default table 202 metric 1 proto static

ip rule add prio 222 table 222
ip route add default table 222 proto static nexthop via $eth0gw dev eth0 weight 1  nexthop via $pppgw dev ppp0 weight 11
