METHOD AND SYSTEM FOR INITIALIZING THE BORDER GATEWAY PROTOCOL ON NETWORK DEVICES

摘要

A method for initializing the border gateway protocol (BGP) on network devices. The method includes initializing, by a first network device, a BPG session with a second network device. The method further includes receiving, by the first network device from the second network device, route updates and an end of routing information base (EOR) marker. The method further includes updating an n_EOR variable maintained by the first network device after receiving the EOR marker and, after updating the n_EOR variable, determining that the first network device has received route updates from all peer network devices, and subsequently updating, in the first network device, a routing information base (RIB) using route updates received from the peer network devices. The method further includes updating, in the first network device, a forwarding information base (FIB) using the updated RIB and advertising, to all peer network devices by the first network device, routes.

1. A method for initializing the border gateway protocol (BGP) on network devices, the method comprising:
initializing, by a first network device, a BPG session with a second network device, wherein the second network device is one of a plurality of peer network devices; receiving, by the first network device from the second network device, route updates and a first end of routing information base (EOR) marker; updating an n_EOR variable maintained by the first network device after receiving the first EOR marker; after updating the n_EOR variable, making a first determination, using the n_EOR variable, that the first network device has received route updates from each of the plurality of peer network devices; after making the first determination:
updating, in the first network device, a routing information base (RIB) using route updates received from each of the plurality of peer network devices to obtain an updated RIB;updating, in the first network device, a forwarding information base (FIB) using the updated RIB;advertising, to the plurality of peer network devices by the first network device, routes, wherein the routes are determined using the RIB.
