Hi People,
I have a router which has 2 ISP connections into it. I have configured an IP SLA to ping an address out the primary ISP interface and install a default route when reachability is up.
The problem is, the reachability status is up, the IP SLA stats are showing successful but it's not installing the tracked route.
See config below:
IP SLA Config to ping 213.94.190.194
CH-BARROW-CMERTR01#sh run | se ip sla
track 1 ip sla 1 reachability
delay down 10
ip sla 1
icmp-echo 213.94.190.194 source-interface FastEthernet0/0
timeout 3000
frequency 3
ip sla schedule 1 life forever start-time now
Shows results as successful
CH-BARROW-CMERTR01#sh ip sla stat

The strange thing is that I have similar config on other sites and they're working fine (I hope) so any advise from a fresh set of eyes would be appreciated.
Thanks in advance,
Neil
