  1. Nice work Rene, just wondering in terms of the default values, the lsa-hold value will never double as the lsa max value is also 5 seconds. So it can never wait longer than 5 seconds before generating a new LSA?

  2. Hello: Why is there a flood sat 35 and 80. I do not see any outstanding LSAs

  3. Hi Ram,

    I understand the confusion, I’ll see if I’ll remove it. The third “flood” arrow is when normally a flood would occur, if an LSA was generated during the 2x LSA hold timer.


  4. hello rene, good job , i am just confuse about lsa arrival timers in command (timers lsa arriver) why i need to set it & how reciever router recieve more than one lsa during 10000, & I am alreay set timers lsa throttle 5000 10000 60000 at sender neighbor router which already postpond flooding operation till 10000 lsa hold times expire.
    high appreciated your feedback

  5. Hello Saif

    Yes you are correct, that if you configure the first router in this particular topology with lsa throttle 5000 10000 60000 you will never have a case where you will receive the same LSA within 10000 milliseconds. However, this command is still useful especially if you are connecting your network with that of another entity using OSPF. You don’t have control over what the other side does, and frankly, you have no reason to trust them. So in order to protect your network, you can and should adjust the lsa arrival timer on your end to be safe.

    I hope this has been helpful!
