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 (L3) connectivity, including detecting a loss of said L3 connectivity; and
(c) to cause the apparatus, in response to said detected loss of said L3 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.

9. 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;wherein said causing the apparatus, in response to the loss of said monitored Network Layer connectivity, to perform DHCP initialization with the particular network address includes causing said initialization despite maintaining Data Link Layer (L2) connectivity on a particular interface of said one or more interfaces, wherein said detected loss of said monitored Network Layer connectivity is on the particular interface.
