What is IP SLA tracking?

What is IP SLA tracking?

An IP service level agreement, or IP SLA, is a network measurement technology that uses active traffic monitoring data to analyze the performance of a network in real time. It collects time-based performance data that actively helps monitor and troubleshoot a network.

How do I track my BGP?

BGP next hop tracking is a feature that reduces the BGP convergence time by monitoring BGP next hop address changes in the routing table. It’s event-based because it detects changes in the routing table. When it detects a change, it schedules a next hop scan to adjust the next hop in the BGP table.

What is IP SLA responder?

Cisco IOS IP SLA (Service Level Agreement) is a tool that can be used to generate synthetic network traffic used for network management. SLA can be configured to send TCP connects, ICMP or even UDP packets.

What is IP SLA used for?

IP SLA was previously known as Service Assurance Agent (SAA) or Response Time Reporter (RTR). IP SLA is used to track network performance like latency, ping response, and jitter, it also helps us to provide service quality.

How do you use IP SLA?

Configuring IP SLA First you need to decide what type of IP SLA operation you want to configure, whether it be ICMP jitter, HTTP GET request, DNS request, VoIP, etc. You then need to configure the IP SLA schedule to tell the IP SLA router when and how often to run the IP SLA operation and also when to stop it.

What is BGP add path?

The BGP Additional Paths feature allows the advertisement of multiple paths through the same peering session for the same prefix without the new paths implicitly replacing any previous paths. This behavior promotes path diversity and reduces multi-exit discriminator (MED) oscillations.

Is BGP a routing protocol?

“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol.”

What is IP SLA threshold?

Timeout sets the amount of time (in milliseconds) for which the Cisco IOS IP SLAs operation waits for a response from its request packet. Threshold sets the rising threshold that generates a reaction event and stores history information for the Cisco IOS IP SLAs operation.

What is the tracking object for IP SLA?

The IP SLA measurement is linked with an object in order to monitor the SLA compliance. The tracking object will be upif the delay is below 10 msec and downotherwise.

When does a static route go into BGP?

You are redistributing statics into BGP. So what happens is that when your MPLS link is up you receive the loopback via BGP and it has an AD of 20 so goes into the IP routing table because it has a better AD. When the MPLS link fails your static route with an AD of 200 is placed into the IP routing table and redistributed into BGP.

Can a Cisco router support IP SLA tracking?

Basic understanding of creating IP SLA and Static Routing.Configuration of IP SLA must be supported on the device and platform. This document is not restricted to specific software and hardware versions. It applies to all Cisco routers that run Cisco IOS and where IP SLA and Track can be configured.

Is there enhanced object tracking of BGP routes?

‎12-13-201301:17 AM Enhanced Object Tracking of BGP Routes We have been assigned by our customer to change all tracking statements to track the routing protocol rather than the line protocol.
