Embodiment Construction

[0013] In some embodiments, the apparatus includes a first network device configured to receive a first forwarding state packet associated with the peripheral processing device and having the first generation identifier from the second network device. The first network device is configured to receive a second forwarding status packet associated with the peripheral processing device and having a second generation identifier from the third network device. The first network device is configured to implement the forwarding state information included in the first forwarding state packet based on the comparison of the first generation identifier and the second generation identifier.

[0014] A generation identifier may be associated with an identifier of a peripheral processing device such that its generation identifier is incremented each time forwarding state information is updated, sent, and / or notified for a particular peripheral processing device . In this way, the first netwo...

Abstract

In some embodiments, an apparatus includes a first network device configured to receive, from a second network device, a first forwarding-state packet associated with a peripheral processing device and having a first generation identifier. The first network device is configured to receive, from a third network device, a second forwarding-state packet associated with the peripheral processing device and having a second generation identifier. The first network device is configured to implement forwarding-state information included in the first forwarding-state packet based on a comparison of the first generation identifier and the second generation identifier.

Description

[0001] Cross-references to related patent applications [0002] This application claims priority and benefit to U.S. Provisional Patent Application No. 61 / 367,811, filed July 26, 2010, entitled "Methods and Apparatus Related to Route Selection within a Network," which is incorporated by reference in its entirety This article. technical field [0003] Some embodiments described herein relate to network connectivity in general and, in particular, to routing within a network. Background technique [0004] Some known network protocols allow routers to exchange forwarding state and / or routing information. When updated forwarding state and / or routing information is received at the router, the router may update and / or store the information to the routing table. Routers that exchange forwarding state and / or routing information using such known network protocols typically rewrite the forwarding state and / or routing information associated with a particular device if the forwarding s...
