Increasing Network Uptime With Redundancy Services

Aruba offers a variety of solutions to provide inter-controller redundancy in a centralized architecture to ensure highly available networks. These solutions can be used by an administrator to implement a highly redundant network depending on the requirements and constraints for each network design. ArubaOS high availability and VRRP Virtual Router Redundancy Protocol. VRRP is an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN. redundancy features allow network administrators to significantly reduce network downtime and client traffic disruption during network upgrades or unexpected failures.

This chapter describes the various redundancy solutions such Mobility Masterredundancy, AP High Availability and VRRP Virtual Router Redundancy Protocol.
