Ip sla question

[Brunhuber Adrian]

Hi,i have a question regarding ip sla. I`m using redundancy between two providers using object tracking.
I want to track icmp echo to an ip but i want to switch to the backup ISP ONLY if the primary ISP is down for more than 3 minutes. (to avoid problems with NAT).
Any help is apreciated.

Thank you.

I think you can do the following. You have:

- a static route to ISP1 with administrative distance AD1. Let's call it route1.

- a static route to ISP2 with administrative distance AD2. Let's call it route2.

AD1 > AD2

The idea is to continually let the SLA ping network of route1. If route1 is unreachable, then the routing table will keep only route2.

try the following:

rtr 1

type echo protocol ipIcmpEcho {IP of ISP1}

timeout 180

frequency 1

rtr schedule 1 life forever start-time now

!

track 101 rtr 1 reachability

!

ip route xxxx xxxx xxxx track 101

how can we create delay of 10 sec when the route goes down and 0 sec when the link recovers

Arvind,

For the continuity of the discussion, please create another thread.

Thanks Wass. The key here was " timeout 180 "
Now it`s working fine.
