    Hello friend, on packet tracer 5.3, I did exactly the same OSPF configurations you did but with different addressing scheme but neither of the 3 routers can see each other. Can't establish any neighbors.

  • @GregSouth
    @GregSouth2 күн бұрын

    Hi @philqurish3114 - Packet Tracer 5.3 is a old version of the software - My recommendation would be to re-create the same addressing scheme that i use in the lab and see if you have the same issue. Other aspects to check why ospf neighbors can't form include: if you haven't named each router with a different router id - as ospf will not form neighbor relationships if the RIDs are the same - in addition, it's worth checking area id (set to 0) and also subnet masks - OSPF requires that interfaces oon the same segment share the same subnet mask. Hope this helps and all the very best. Thanks,Greg

    @GregSouth NTP distribution is one I haven't found any great explanations for. Particularly where multiple switches are involved. As for some other topics maybe configuring interVLAN routing when trunked to a VM hypervisor. That seems to trip people up. I've found turning on/off debugging features tends to be hard to understand for people also.

    Hi @maxirocitrizus4516 - be careful with the subnet masks you on the serial links - you will note they are /30. If you assigned them with /24 it would cause an issue with IP's overlapping. Hope this helps, Greg
