[c-nsp] Trigger Backup With Cisco SLA

[Anton.Schweitzer at o2.com]

Hi,

is anbody here using Cisco Object Tracking for triggering backup 
connections and can share experiences for a huge
amount of devices, timing etc?

We want to use IP SLA to Ping 3 different Hosts, when 2 of them fail then 
we switch to the backup connection.

ip sla 2
 icmp-echo 1.1.1.1 source-ip 192.168.101.1
 timeout 1000
 threshold 500
 frequency 3
ip sla schedule 2 life forever start-time now
ip sla 3
 icmp-echo 1.1.1.2 source-ip 192.168.101.1
 timeout 1000
 threshold 500
 frequency 3
ip sla schedule 3 life forever start-time now
ip sla 4
 icmp-echo 1.1.1.3 source-ip 192.168.101.1
 timeout 1000
 threshold 500
 frequency 3
ip sla schedule 4 life forever start-time now
