IP sla tracking, how can I make the hold down/up timer longer?

[jackawang]

Pretty standard IP sla tracking configuration as below. I realized that 180 seconds is the maximum timer I can configure in "delay down 90 up 180". What if I want it to stay down for 4 hrs before claims up?

ip sla 1

icmp-echo 4.2.2.2

timeout 1000

frequency 3

ip sla schedule 1 life forever start-time now

track 1 rtr 1 reachability

delay down 90 up 180

hi,

EOT is about tracking the network's behavior and prevent traffic loss n blackholes, so fast convergence with minimum down time is definitely an objective. this delay option that you have here is a part of insurance, when there is a possibility of link flapping.

well, i dont think you can keep a link down for such long time using object tracking, maybe an script n timer can do that.

plz Rate if it helped,
