CONTAP-461406: [RFE] Network route create validation for matching destination and metric
Issue
This is an RFE to emit a warning when multiple routes are created with the same destination and the same metric.
The metric is used by the network stack to favor one route over another. If routes with the same destination have the same metric, that indicates to the network stack those routes will be weighted equally and none will be favored. This is a valid routing configuration.
We do not emit warnings or error for valid network configurations as it can be confusing to administrators.
For this reason, the RFE will is closed and will not be implemented.
