Best Practice to add a Secondary WAN?

[Roey1984]

Hello

We have an office with 35 users with the following hardware:

Cisco Meraki MX75

Cisco Meraki MS120 x2

Cisco Meraki MR46 x5

Primary uplink of 200 \ 200 Mbps.

A secondary uplink - is being deployed now.

What best practices should I follow to configure the Secondary Uplink as a spare? (in case the primary goes down, I want the secondary to failover)

Is it ok to change or edit  the IP address of the secondary uplink via the Dashboard? or should I do it only via the local status page?

According to Meraki Support:

"Note: Modifying the state (enabled/disabled) or addressing method (static/DHCP) of a WAN connection from Dashboard causes both WAN interfaces to reset, which results in a loss of connectivity on both Internet uplinks for up to 2 minutes. Therefore, it is recommended to only make changes during a planned maintenance window so that disruption is minimal."

Thank you!

The first question is all your choice. Personally I like the primary/backup approach as long as the primary link is not saturated. Having no load-sharing makes troubleshooting much easier. But if you go to the max of ISP1 *and* both uplinks are equally fast, I would use load-sharing.

You can configure on the dashboard or on the local status page.

Just configure WAN 2 that won't cause any outages.
