IP SLA config sets up IP SLA (Service Level Agreement Monitor) as active monitoring feature which allows to determine connectivity in two ways. Firstly, by checking IP destination availability. Secondly, by measuring specific parameters of the network along the given path. IP SLA config is commonly used for performance statistics like Delay, Jitter or Packet Loss in SP and Enterprise environments. However here you can see the example of achieving the WAN redundancy in the easy way (i.e. without dynamic routing protocol implementation) using IP SLA.
Define the ip SLA, protocol type, destination and source:
Ip Failover Solutions
Configure the SLA monitor with ID 10 ASA (config-sla-monitor)# type echo protocol ipIcmpEcho 8.8.8.8 interface outside Configure the monitoring protocol, the target IP for the probe and the interface use SLA monitor will keep probing the IP we define here and report if its unreachable via the given interface. Basic understanding of creating IP SLA and Static Routing.Configuration of IP SLA must be supported on the device and platform. Components Used. This document is not restricted to specific software and hardware versions. Wondershare video editor full. It applies to all Cisco routers that run Cisco IOS and where IP SLA and Track can be configured.
Router(config)#ip sla 1
Router(config-ip-sla)#icmp-echo 10.10.10.1 source-interface FastEthernet1/0
Probing parametrs :
Router(config-ip-sla-echo)#timeout 2000
Router(config-ip-sla-echo)#frequency 5
Router(config-ip-sla-echo)#threshold 250
Run the probing:
Router(config)#ip sla schedule 1 start-time now life forever
Ip Failover Linux
Define tracking that will result with TRUE or FALSE depending on IP SLA status:
Router(config)#track 10 ip sla 1 reachability
Bidning the track to static route:
Router(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.1 track 10
Configuring the alternate route in case of primary is removed by track result:
Router(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.2 5

Track command next to particular route determines the route presence in routing table. If there is no echo response according to given parameters (IP SLA) the track statement takes the FLASE value and the route is removed from routing table leaving the lasting static route that uses another next hop thus assuring redundancy.
