3.1.3 Initialization

When the DHCP server is booting after shutdown, or a new failover relationship has been configured between the two failover servers, the state of the failover endpoint MUST be set to STARTUP and the Startup timer SHOULD be set as specified in section 3.1.2.

If this is a new failover relationship created between the two servers, after the communication has been established with the partner server, the DHCP server MUST transition both failover endpoints to the RECOVER state.

Otherwise, after the communication has been established with the partner server, the failover endpoint MUST transition to the communication-failed state indicated by the prevState member of the shared DHCPv4FailoverRelationship ADM element ([MS-DHCPM] section 3.1.1.33). The communication failed state is depicted in the Failover state machine figure in section 3.1.1.
