SD-WAN device support "legacy" routing?

[frank.gerlipp]

Hello all,

We have a need to implement a "legacy" routing solution at a branch office that will transition to SDWAN in the future. Is it possible to use a 8200/8300 (or another device) in this "legacy" routing mode and then reconfigure to SDWAN when it is implemented in the future?

Thanks

Hello Frank,

Starting with Cisco IOS XE Release 17.2.1r, you can use the universalk9 image to deploy both Cisco IOS XE SD-WAN and Cisco IOS XE on Cisco IOS XE devices.

Switch Between Controller and Autonomous Modes Using Cisco CLI

Use the controller-mode command in Privileged EXEC mode to switch between controller and autonomous modes.

The controller-mode disable command switches the device to autonomous mode.

Device# controller-mode disable

The controller-mode enable command switches the device to controller mode.

Device# controller-mode enable

I hope this helps.
