    May you pls explain same scenario adding 2 switches and 2 routers in between.

    Computer A -------Switch1-----ROUTER1------------------ROUTER 2 ---- Switch2 ----- Computer B.

    Much Thanks !!

  2. Hi Virender,

    When Computer A wants to reach Computer B it will have to know how to reach its default gateway because both computers are in a different subnet. What happens is that Computer A will do an ARP request for the IP address of Router 1 (its default gateway).

    Computer B will do an ARP request for Router 2 (its default gateway).

    Router 1 and Router 2 will do ARP requests on the link that connects them to discover each others MAC addresses.


  3. Hi Rene ,

    Yes i am not able to ping any of those which shows as incomplete.
    I was not getting an answer from anyone on this and finally i got it from you. Thanks Rene .


  4. Hi Rene,

    Thanks for your reply and explanation. How about this scenario below:

    A send C an ARP request
    C send A an ARP reply
    ** C also records down A arp request information in its ARP cache, so that it does not need to send A an ARP request in the near future.

    ** - Does C does that ? or does it send a separate ARP request to A ?

  5. Guess its somewhat clear. Thanks a lot Rene.
