- One of the shortcomings of DHCP lies in achieving truly redundant server operations. Using multiple servers in a single network typically requires separate address pools and frequently results in duplicate address assignments and inefficient address usage. Recent work in the Internet Engineering Task Force's DHC Working Group has been addressing this shortcoming with the development of the DHCP Failover protocol. This session discusses this protocol and how it safely allows two servers to work together (and independently) in assigning addresses to clients without duplication and using a common address pool. The session also highlights how the servers coordinate lease activity, continue to operate even in difficult situations, such as network partitioning and server failures, and synchronize after a failure.
