  1. Hi Rene,
    I have a question. What is the difference between composite metric and vector metric in EIGRP?
    I see both the metric when I issue the command “sh ip eigrp x.x.x.x”

    I appreciate if you can visualize me the difference between them.

    Regards,
    Mallik

  2. Hello Mallik,

    Although I am not Rene, I hope I can help you out. From what I understand vector metrics are the metrics that in total make up the composite metric. For example Bandwidth, Delay, Load, Reliability, and MTU are the Vector Metrics. Together they are used in a formula to find the composite metric. This composite metric is used by EIGRP to decide the best paths to insert into the topology and routing table.

    Thanks!
