**Soft reconfiguration inbound** Allows policy changes without resetting the session by storing inbound updates.
**BFD** Enable Bidirectional Forwarding Detection (BFD) for rapid link failure detection with the neighbor.
**Keepalive** Sets the interval (default 60 seconds) between keepalive messages to check the neighbor's availability.
**BFD Strict Mode** Strict mode requires the BFD session to be established before allowing BGP to connect.
If BFD goes down, BGP immediately closes the session.
This prevents BGP sessions from remaining up when the underlying link is down. Requires BFD to be enabled.
**Hold Down Time** Time (default 180 seconds) before declaring a neighbor down if no keepalive messages are received.
**Connect Timer** Interval to attempt reconnecting with a neighbor after a disconnect.
**Send Defaultroute** Sends a default route to the neighbor, useful in small AS environments where a full routing table is not necessary.
