Abstract

A system and method for synchronous configuration of DHCP server and router interfaces is disclosed. A network management layer identifies a DHCP server interface and a router interface associated with the same subnet. The network management layer then determines configuration information for the DHCP server interface and the router interface. The DHCP server and the router are programmatically configured with the determined configuration information.

Claims

1. A network comprising:

a router having a router interface associated with a subnet;

a DHCP server having a DHCP interface associated with the subnet; and

a node coupled with the router and the DHCP server and having a processor and logic executable thereon to

reference an electronic file to determine whether a DHCP server interface and a router interface are on the same subnet; and

determine configuration information for the DHCP server interface based, at least in part, on information in the electronic file; and

determine configuration information for the router interface based, at least in part, on information in the electronic file.

2. The network of claim 1, wherein the referenced electronic file comprises a list of network components having a standardized syntax.

3. The network of claim 2, wherein the electronic list of network components includes addressing scheme information to identify an addressing scheme for the listed network components.

4. The network of claim 1, wherein the node coupled with the router and the DHCP server and having a processor and logic executable thereon to automatically determine configuration information for the DHCP server interface based, at least in part, on information in the electronic file comprises logic executable to

determine an IP address of the DHCP server interface;

and

determine a gateway IP address for the subnet.

5. The network of claim 1, wherein the node coupled with the router and the DHCP server and having a processor and logic executable thereon comprises logic executable thereon further to

programmatically configure the router with the determined configuration information;

and to

programmatically configure the DHCP server with the determined configuration information.

6. The network of claim 1, wherein to node is the DHCP server.

7. A network comprising:

a router having a router interface associated with a subnet;

a Bootstrap Protocol (BOOTP) compliant server having an interface associated with the subnet; and

a node coupled with the router and the BOOTP compliant server and having a processor and logic executable thereon to

reference an electronic file to determine whether a BOOTP compliant server interface and a router interface are on the same subnet; and

automatically determine configuration information for the BOOTP compliant server interface based, at least in part, on information in the referenced electronic file; and

automatically determine configuration information for the router interface based, at least in part, on information in the referenced electronic file.

8. The network of claim 7, wherein the referenced electronic file comprises a list of network components having a standardized syntax.

9. The network of claim 7, wherein the node coupled with the router and the BOOTP compliant server and having a processor and logic executable thereon comprises logic executable thereon further to

programmatically configure the router with the determined configuration information;

and to

programmatically configure the BOOTP compliant server with the determined configuration information.
