Redundancy is a key component of the Meraki MS layer 3 implementation. First, OSPF’s native routing resilience automatically adapts to detected link failures—preventing vital resources from becoming unreachable if alternative pathways to it exist. Second, built-in warm spare redundancy ensures that downtime and disruption are minimized in the event of physical switch failure. Finally, integrated DHCP service and relay can be enabled on layer 3 Meraki switches, ensuring that if the only accessible DHCP server on a network segment becomes unavailable, addressing service can be restored. In fact, if an MS switch hosting DHCP service fails over to a warm spare, DHCP service will seamlessly transition to the backup switch.
