An administrator supports Aruba Mobility Controllers (MCs) managed by a Mobility Master (MM) in a non-cluster deployment. The administrator performs these tasks on the MM for the MCs:
• Enables L3 IP mobility for the respective VAPs on the MCs
• Creates a L3 domain and places the MCs in the domain
However, roaming does not work when users roam from an AP connected to one controller in the domain to an AP connected to a different controller in the domain.
What must the administrator do to fix this problem?
