Receiving a DHCP Failover BNDACK Message

When a DHCP server implementing this specification receives a BNDACK message with multiple lease update responses in a single message, the order of the assigned IP Address option in the BNDACK message and the corresponding order in the BNDUPD message MUST be validated to be the same. If the order is different, the BNDACK message MUST be dropped.

The BNDACK message MUST be processed as specified in [IETF-DHCPFOP-12] section 7.2.2.
