1. An apparatus, comprising:
- one or more network interfaces configured to communicate over a network, including with a Dynamic Host Configuration Protocol (DHCP) server; and
one or more processing elements configured;
(a) to set one or more network communication values of the apparatus using DHCP in communication with the DHCP server, with said one or more communications values including a particular network address;
(b) to monitor Network Layer (Layer
3) connectivity; and
(c) to cause the apparatus, in response to a loss of said monitored Network Layer connectivity, to perform DHCP initialization with the particular network address.

Abstract
Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with loss of network layer connectivity triggering Dynamic Host Configuration Protocol (DHCP) initialization. According to one embodiment, a network device connected to a network initializes one or more network communication values of the network device using DHCP. The network device monitors Network Layer (Layer 3) connectivity with a remote network device; and in response to detecting a loss of said monitored Network Layer connectivity, DHCP initialization of the network device is performed.
