Enabling multipath routing

If multiple routes have the same metric for a destination, only one of the routes is picked for outgoing traffic. This leads to other routes being unutilized for sending outgoing traffic. Starting with ONTAP 9.5, you can enable multipath routing to load balance and utilize all the available routes.

Steps

  1. Log in to the advanced privilege level: set -privilege advanced
  2. Enable multipath routing: network options multipath-routing modify -is-enabled true
    Multipath routing is enabled for all nodes in the cluster.
    Example
    cluster1::*> network options multipath-routing modify -is-enabled true
