Patent ID: 7505402

Claim:
A method of providing convergence for a dual-homed site in a network, the method comprising: detecting an occurrence of a failure between a first Provider Edge (PE) device and a first Customer Edge (CE) device in communication with said dual-homed site; and determining whether an alternate route exists for said dual-homed site in a routing table associated with said first PE device, and when an alternate route exists then: keeping a routing entry associated with said first CE device in a routing table of said first PE device from being deleted for a predetermined amount of time after said detecting a failure wherein said predetermined amount of time is longer than a time required for the convergence to complete; modifying said routing table to reference said alternate route; rewriting the routing entry to perform a popping and lookup in a Virtual Routing and Forwarding (VRF) table of said first PE device; and deleting said routing entry after said predetermined amount of time has elapsed.
