When must both the ip forward-protocol and ip helper-address commands be entered on a Cisco device during a WLC deployment in order to successfully forward CAPWAP Discovery Requests?

When must both the ip forward-protocol and ip helper-address commands be entered on a Cisco device during a WLC deployment in order to successfully forward CAPWAP Discovery Requests?

• when a router is positioned between the WLC and the lightweight AP
• when an access switch is positioned between the WLC and the lightweight AP
• when a WLC is deployed within a centralized WLAN network topology
• when a WLC is deployed using an embedded access switch

Explanation: A Cisco router separates broadcast domains and will prevent broadcasted CAPWAP Discovery Requests from being forwarded between a WLC and an access point. The ip forward-protocol and ip helper-address commands must be entered on the Cisco router to enable the forwarding of broadcast traffic to the specified WLC.
