Hello again,
So... We have 2 ISP's, one primary, and one backup. We want our default route to point to the primary (of course), but if it is no longer reachable, to failover to the backup ISP. BUT when the primary comes back online, will this configuration automatically shift the default gw back to the primary ISP? I can't find anthing that says it will, but I'm not sure. If not, then how can we make sure this happens?
It's my understanding that we can't use "qualified next-hop" because that is based on link-state, and our srx's are connected to our switches via Reth's, then to the ISPs.
Here is part of the config:
rmckennon@gnv-srx220# show routing-instances PRIVATE
instance-type virtual-router;
interface reth0.400;
interface reth1.10;
...
interface st0.0;
routing-options {
static {
route 0.0.0.0/0 next-hop xx.yy.zz.193;
}
}
rmckennon@gnv-srx220# show services
rpm {
probe COX {
test GW-TEST {
target address xxx.yyy.zzz.193;
probe-count 10;
probe-interval 5;
test-interval 10;
thresholds {
successive-loss 10;
}
traps probe-failure;
destination-interface reth0.400;
}
}
}
ip-monitoring {
policy COX-MONITOR {
match {
rpm-probe COX;
}
then {
preferred-route {
routing-instances PRIVATE {
route 0.0.0.0/0 {
next-hop aa.bb.cc.105;
}
}
}
}
}
}
Thank you for looking,
Rob McKennon
