Topology With IP Addressing

BGP Next Hop Self lab topology with IP addressing details, featuring three routers: R1 (AS1), R2 and R3 (AS23)
The last octet is the router number unless specified otherwise. Example: R1's G0/0 is Access to the initial configs, EVE-NG lab file and solution is below.


By default, BGP updates sent to iBGP peers don’t modify the next-hop. This can cause problems if a router doesn’t know how to reach that next hop. If the recursive lookup for the next hop fails the prefix will not be considered for best path selection and will never make it to the routing table. In this lab you’ll see this problem from R3’s perspective and fix it using the BGP next-hop-self feature
