How can you change the trusted interface IP address without causing a network outage?

Changing the trusted interface IP address without causing a network outage can be effectively achieved by adding the old IP address as a secondary IP address for the interface. This method allows devices on the network to continue communicating using the old IP address while you transition to the new one.

By configuring the new trusted IP address as the primary address and keeping the old IP address active as a secondary address, devices that are configured to communicate with the old address will not experience any disruption. They will still be able to send and receive data, allowing for a seamless transition. During this period, you can gradually update network devices to recognize and utilize the new IP address.

Once all devices have migrated to the new IP, the secondary old IP can be removed without any outages, ensuring that the network continues to function smoothly throughout the process. This approach minimizes the risk of a network downtime commonly associated with abrupt IP address changes.
