Automated network device provisioning using dynamic host configuration protocol

摘要

In an embodiment, an electronic digital data packet router performs receiving a DHCP initiation message on a particular interface among a plurality of network interfaces; modifying the DHCP initiation message by adding a particular DHCP option that signals a DHCP server to provide router configuration data, resulting in a modified DHCP initiation message; relaying the modified DHCP initiation message to the DHCP server; receiving, from the DHCP server, a DHCPOFFER message that comprises the particular DHCP option containing configuration data; configuring the router using the configuration data; relaying the DHCPOFFER message without the particular DHCP option on the particular interface toward another data packet router.

主权项

1. A data packet router, comprising:
a plurality of network interfaces; one or more hardware processors coupled to the network interfaces; dynamic host configuration protocol (DHCP) relay agent logic coupled to the one or more hardware processors, wherein the logic is configured to perform upon execution:
receiving a DHCP initiation message on a particular interface among the plurality of network interfaces;modifying the DHCP initiation message by adding specified provider edge (PE) router configuration data and a particular DHCP option that signals a DHCP server to validate the specified PE router configuration data, resulting in a second modified DHCP initiation message;relaying the second modified DHCP initiation message to the DHCP server;receiving, from the DHCP server, a DHCP response message.
