  1. Hello Bahri

    I assume it is this topology that you are talking about:


    Essentially, the three routers are connected not as a point to point connection (obviously, since there are more than two interconnected devices), but as a multiple access network. This multiple access network can be interconnected by switches or any number of layer two devices. So in between the three routers there can indeed be a switch or any number of switches interconnecting these r

    That means both inside Routers have default to ISP, but when 1 inside Router chrashes, BGP is not deleted between inside Routers. EIGRP

  5. My bad. Indeed oldest path is selected before router ID. :slight_smile: Many thanks Rene!
