Patent ID: 7894462

Claim:
A backbone network comprising: a first border router providing data connectivity between the backbone network and a first regional network wherein the first border router is configured to receive a notification of a change in status of an edge router of the first regional network wherein the notification is received according to a first routing protocol, and to redistribute the notification of the change in status of the edge router from the first routing protocol to a second routing protocol wherein the first and second routing protocols are different; a second border router providing data connectivity between the backbone network and a second regional network; and a route reflector coupled between the first and second border routers wherein the route reflector is configured to transfer the redistributed notification from the first border router to the second border router, wherein the first border router comprises: a first OSPF Link State database associated with a first router interface, wherein the first OSPF Link State database is provided according to the first routing protocol, and wherein the first router interface is configured to update the interface based on the change in status of the edge router responsive to receiving the notification of the change in status of the edge router of the regional network; a second OSPF Link State database associated with a second router interface, and wherein the first router interface is configured to update the first OSPF Link State database based on the change in status of the edge router without the second interface updating the second OSPF Link State database based on the change in status of the edge router; and a Border Gateway Protocol database associated with the second router interface wherein the second router interface is configured to update the BGP database based on the change in status of the edge router responsive to the second router interface receiving the redistributed notification.
