Low levels of packet loss at the first hop inside a providers network can sometimes indicate a connection thats struggling to maintain service. This might be because of noise on the line or marginal hardware. Water in a junction box is one example, or maybe a bad splitter or terminator on a cable modem line. Discuss how redundancy through HSRP helps ensure that user traffic immediately and transparently recovers from first hop failures in network edge devices or access circuits.
For your citations, you might use articles that show examples of HSRP recovering network traffic in the specific situations mentioned in the prompt. You can also find articles from experts that suggest best practices for using HSRP in network edge devices or access circuits.
