![]() ![]() ![]() So this border router announces prefixes learned from ISP1 to your route reflector (RR1) - the next hop of each such prefix will be 192.0.2.65. So if you have some Border router connected to an ISP on a circuit addressed as 192.0.2.64/30, for instance, then 192.0.2.64/30 would need to be reachable in your OSPF. IBGP does not modify the next hop address when it propagates prefixes. Most likely your border routers' Internet attachement circuits' IP ranges are not being advertised into your OSPF. Hello, my routes learned by RR appear unreachable in the peers, why is that? What do you think? Am I going about this the right way or should I use another protocol such as OSPF for my internal routes and just redistribute them into BGP where I connect to my upstream providers? This doesn't seem to be quite right and from what I have been reading I need to designate only several routers as route reflectors and not all of them, but I'm not sure how the best way to do this is. I originally thought that this would be as simply as turning on route reflect on every ibgp peer and making sure each bgp instance (one per router with our AS #) had client to client reflection turned on. Rather than meshing the entire IBGP network (which would result in hundreds of peers) I assumed we could just turn on route reflection, but this seems easier said than done. We currently are running into issues with the latest couple routers getting some recursive routes and routing loops for some of the new ibgp advertised networks. We are planning on solely using BGP for routing on this network. ![]() Does anyone have a good link on how to properly configure BGP route reflectors on Mikrotik OS? We will eventually have about 15 MikroTIk RouterOS routers running ibgp peers between them and are trying to get all our full internet Ebgp routes (from several upstream providers) and internal iBGP routes to properly propagate across the entire network. ![]()
