Cisco IP SLA: Tracking A Static Route [WAN Redundancy]
Posted by Ahsan Tasneem | 4:35 AM | cisco, IP SLA, SLA | 0 comments » In today's network environment, redundancy is one of the most important aspects, whether its on the LAN side or on the WAN side. In this topic I will be covering WAN redundancy with multiple WAN links terminating on a single router.
The best and simplest way to achieve WAN redundancy on Cisco devices is to use Reliable Static backup routes with IP SLA tracking.
IP SLAs is a feature included in the Cisco IOS Software that can allow administrators the ability to Analyze IP Service Levels for IP applications and services. IP SLA's uses active traffic-monitoring technology to monitor continuous traffic on the network. This is a reliable method in measuring over head network performance. Cisco Routers provide IP SLA Responders that give accuracy of measured data across a network.

Cisco IOS IP SLAs can send SNMP traps that are triggered by events such as the following:
• Connection loss
• Timeout
• Round-trip time threshold
• Average jitter threshold
• One-way packet loss
• One-way jitter
• One-way mean opinion score (MOS)
• One-way latency
Alternately, an Cisco IOS IP SLAs threshold violation can trigger another Cisco IOS IP SLAs operation for further analysis.
The Cisco IOS IP SLAs MPLS VPN Awareness feature provides the capability to monitor IP service levels within Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs). IP SLAs operations can be configured for a specific VPN by specifying a VPN routing and forwarding (VRF) name.
