** If the router was unable to establish a successful TCP session, then it ends up in the Active state.

** If there is an error it is because one of the fields in the Open message doesn ’ t match between the peers, e. g. BGP version mismatch, MD5 password mismatch, the peering router expects a different My AS.

** If a timer expires before a Keepalive message is received, or if an error condition occurs, the router transitions back to the Idle state.

** If a timer expires before a Keepalive message is received, or if an error condition occurs, the router transitions back to the Idle state.

If the router does not have a route to that destination from any non-BGP source, the withdrawn route will be removed from the main routing table.

If you add rules to take flow statistics out of the router during the DoS attacks, they further slow down and complicate the matter.

If packets arrive faster than the router can process them ( such as in a burst transmission ) the router puts them into the queue ( also called the buffer ) until it can get around to transmitting them.

If the traffic intensity is less than one erlang, then the router can handle more average traffic.

If the router does not know how to forward the packet, it typically drops the packet.

If it knows how to forward packet, it changes the destination physical address to that of the next hop router and transmits the packet.

If not explicitly configured, the highest logical IP address will be duplicated as the router identifier.

If no router is DR or BDR on a given subnet, the DR is first elected, and then a second election is held if there is more than one BDR.

* If the priority setting on an OSPF router is set to 0, that means it can NEVER become a DR or BDR ( Backup Designated Router ).

* If two or more routers tie with the highest priority setting, the router sending the Hello with the highest RID ( Router ID ) wins.

If, for a destination, a neighbor router advertises a distance that is strictly lower than our feasible distance, then this neighbor lies on a loop-free route to this destination.

If, for a destination, a neighbor router tells us that it is closer to the destination than we have ever been, then this neighbor lies on a loop-free route to this destination.

If the packet traverses an Active Queue Management ( AQM ) queue ( e. g. a queue that uses Random Early Detection ( RED )) that is experiencing congestion and the corresponding router supports ECN, it may change the codepoint to instead of dropping the packet.

If the servers die, the router will automatically withdraw the announcement.

If a host tries to send data through a router ( R1 ) and R1 sends the data on another router ( R2 ) and a direct path from the host to R2 is available ( that is, the host and R2 are on the same Ethernet segment ), then R1 will send a redirect message to inform the host that the best route for the destination is via R2.

If the path message arrives at a router that does not understand RSVP, that router forwards the message without interpreting the contents of the message and will not reserve resources for the flow.

If the host is configured to forward packets for other clients, often a local network, it is then a router.

If the operating system detects that a program has tried to alter memory that does not belong to it, the program is terminated.

If the spacecraft detects an anomaly, it changes the carrier between four tones, based on urgency.

: If the watch-dog detects an intruder, the dog will bark.

If an internal monitor detects radioactivity, the flask is shattered, releasing the poison that kills the cat.

If a receiver is connected to the system in the middle of a frame transmission, it ignores the data until it detects a new frame synchronization sequence.

If a more general measurement is made that detects the system in a state then the system makes a " jump " or quantum leap from the original state to the final state with probability of.

If the variables are independent, Pearson's correlation coefficient is 0, but the converse is not true because the correlation coefficient detects only linear dependencies between two variables.

If the sentinel detects a predator, it gives a loud alarm to warn the troop and indicate whether the threat comes from the air or the ground: if from the air, the meerkats rush to the nearest hole ; if from the ground, the troop flees.

* If Gyakuten Kenji 2 detects a pirated or downloaded copy of the game, it will convert the entire game's text into the game's symbol based foreign language, Borginian, which cannot be translated in any way.

If it detects any traffic prior to its own greeting ( in violation of RFC 2821 ) it closes the connection.

If the Built-In Test equipment detects a fault the missile will be returned to MBDA for repair.

If the aircraft detects the targeting laser, it has the whole period of the missile flight time to engage in avoidance maneuvers, which adds additional challenge to the missile operator's target-tracking task.

If the saw detects a change in this current ( as would occur if a hand or other body part came into contact with the blade ) an automatic braking system is activated, forcing an aluminum brake block into the blade.

If it detects that the program has tried to hook into DOS, it will jump back into the 16-bit code to let the hook run.

If the processor detects a protection violation, it stops executing the code and sends a GPF interrupt.

If a home fecal occult blood test detects blood in the stool it is recommended to see a health professional to arrange further testing.

If the disk drive detects multiple read errors on a sector it may make a copy of the failing sector on another part of the disk-remapping the failed sector of the disk to a spare sector without the involvement of the operating system ( though this may be delayed until the next write to the sector ).

If the left wheels are on asphalt and the right wheels are on ice, during an emergency stop, ABS detects the right wheels about to lock and reduces braking force on the right wheels, helping to avoid lock-up and loss of vehicle control.

If the yaw sensor detects more / less yaw than the steering wheel angle should create, the car is understeering or oversteering and ESC activates one of the front or rear brakes to rotate the car back onto its intended course.

If it detects something, it will alert the operator.

If this step detects a negative cycle, the algorithm is terminated.

If a system failure causes data corruption then when the MKDE is restarted it detects all the files that had a failed system transaction and tried to recover them.

If the link layer receiver detects a CRC error, the receiver notifies the transmitter via a flit on the return link of the pair and the transmitter resends the flit.

If it detects an answering machine, the dialer hangs up.
