Zusammenfassung:	A networking system may facilitate Border Gateway Protocol (BGP) switchover between an active BGP process and a standby BGP process. A method is provided that includes using the active BGP process to establish a first communication session with a peer and a second communication session with the standby BGP process and using an active kernel associated with the active BGP process to receive a packet from the peer, to transmit the packet to the standby BGP process, and to receive the packet returning from the standby BGP process. The active kernel can optionally be used to determine whether any packets are in-flight to and from the standby BGP process.
