SLA Monitoring Problem/Question

[gkonheiser]

Hi there

I have two SLA ICMP Echos set up to monitor my 2 ISPs. I am using 4.2.2.2 and 213.165.64.75 as my destinations and have the following routes inplace:-

ip route 0.0.0.0 0.0.0.0 212.243.229.25

ip route 0.0.0.0 0.0.0.0 62.2.48.37 20

ip route 4.2.2.2 255.255.255.255 212.243.229.25

ip route 8.8.8.8 255.255.255.255 62.2.48.37

the Problem im having is that when  I am pinging 8.8.8.8 and the route 62.2.48.37 goes down it reroutes to 212.243.229.25 hence the SLA echo will always show as up. 

Thanks for any help.

Hi Gordon,

When you specify the ip route to the individual addresses, specify the permenant tag on the end of them

ip route 4.2.2.2 255.255.255.255 212.243.229.25 permanent

ip route 8.8.8.8 255.255.255.255 62.2.48.37 permanent

This will ensure that the route stays in the routing table, even if the interface goes down.
