  1. Hi Rene,
    So, Here BGP identified event by OSPF and update next hop after 5 sec but how BGP identified event between two eBGP Router that are not directly connected .Between eBGP Router there is a L2 segment . So My Question is in the scenario how BGP detect & update next hop. It will takes max 60 sec , right ? Thanks

    Remember that a BGP neighbourship can be formed between two BGP routers even if they are not directly connected. The only prerequisite is that there is adequate routing between them (using IGPs) so that they can exchange BGP information. So, even in that case, if the routing table of a BGP router changes and the route to the other BGP router becomes unavailable, the change in the routing table will take place which will indeed trigger the BGP next hop tracking mechanism.

    I hope this has been helpful!

So in between the three routers there can indeed be a switch or any number of switches interconnecting these r
