I need improve my ip sla icmp based for backup

[david.sua]

Hi all,

I use ip sla for backup routes with this example config:

ip sla 1

icmp-echo 33.33.3.3 source-ip 88.88.8.8

timeout 3000

threshold 3

frequency 10

ip sla schedule 1 life forever start-time now

track 123 rtr 1 reachability

ip route 0.0.0.0 0.0.0.0 ATM0.1 track 123

ip route 0.0.0.0 0.0.0.0 FastEthernet0 22.22.22.1 200

then when ping to 33.33.3.3 fail, the first route disappear and second one through FastEthernet0 is my default gateway.

This happend with the first failed packet but i would like that happend after 3 failed pings.

Somebody can help me?

Regards!

You can add the following under your track:

delay down 30

This will delay setting the track object to down for 30 seconds. If, after 30 seconds, it's still down, then the track will go down, and your route will disappear.
