Good day Friends,
I have the below network setup
Corporate Router -> Dsl modem -> Telco cloud -> Head Quarters
As a backup, we have ISDN link.
Now,we have setup IP SLA track to use ICMP echo to ping a server in headquaters. And if there is no reply, to trigger the ISDN.
Now the problem is, since we are using DSL connection, out of 15 or 20 pings, there is 1 timeout even though the connection is up. IP SLA just considers this 1 timeout and triggers the ISDN thinking that the DSL link is down.
So i am looking for a way in which IP SLA considers about 3-10 timeouts before triggering the backup ISDN.
Thanks in advance for your inputs.
You need to use the 'track' feature also.
track 123 rtr 1 reachability
delay down 120 up 60
ip sla schedule 1 life forever start-time now
120/60 are in seconds.
With teh above statement, incase if the A.B.C.D not available for 2Mins, it will take backup backup path. When A.B.C.D reachable again , in 1Min, it fall back to original path.
