A method for initializing the border gateway protocol (BGP) on network devices. The method includes initializing a plurality of BGP convergence variables corresponding to a plurality of BGP sessions with a plurality of peer network devices. The first network device initializes the plurality of BGP sessions with the plurality of peer network devices, and receives from each of the plurality of peer network devices, route updates and a plurality of markers. The BGP convergence variables are updated and it is determined that first network device has received all the route updates. The duration of the BGP session is less than a C_TIMEOUT value for that peer network device, exceeds an I_P_TIMEOUT value, where the C_TIMEOUT value is greater than the I_P_TIMEOUT value. The first network device updates a routing information base (RIB) using the route updates and updates a forwarding information base (FIB) using the updated RIB.

Method and system for initializing the border gateway protocol on network devices

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.
