Overriding the IP address and port for connecting an interface to the SD-WAN controller

You can connect WAN interfaces to the SD-WAN Controller even if they use different types of communication channels, for example, the Internet vs a private MPLS network (see the figure below). In this case, you need to manually override IP addresses and ports for connecting to the Controller when creating or editing interfaces.

Connecting the CPE device to the Controller via two different communication channels

If your SD-WAN instance uses multiple Controller nodes, you must override IP addresses for all nodes. If the number of SD-WAN Controller nodes does not match the number of specified IP addresses, an error occurs and the values stay the same.

After overriding the IP address and port for connecting the interface to the SD-WAN Controller, you must restart the CPE device.
