Abstract
A networking system may perform a border gateway protocol (BGP) switchover from an active BGP process to a standby BGP process. The standby BGP process may obtain transport layer protocol state information, for a given time, of a transport layer session for the active BGP process. The standby BGP process may update the transport layer protocol state information based on BGP messages conveyed, after the given time, over the transport layer session and forwarded to the standby BGP process. Based on a BGP switchover criterion being met, a replacement transport layer session may be set up using the updated transport layer protocol state information. The replacement transport layer session continues the transport layer session after the BGP switchover.
