  • Extending sso for DHCP snooping to two box redundancy
    Patent number: 7903647
    Abstract: Disclosed are mechanisms for facilitating the use of DHCP (dynamic host configuration protocol) binding data. In general, certain applications include mechanisms for intercepting data being sent from a node and then determining whether the data corresponds to a valid IP address and MAC address binding. Embodiments of the present invention provide mechanisms for sharing such DHCP binding data between routers (or other type of network devices) in a redundancy group so that any of the routers may take over the data inspection to validate DHCP bindings. In particular aspects of the invention, the DHCP binding data is validated in procedures related to DHCP snooping, dynamic ARP (address resolution protocol) inspection, and the like.
