That's because of my "lack of understanding" the way RR actually works.Īs you well see I want to propagate full routes between the routers and then, depends on various things, for example link capacity, choose route on. I tried lots of different configurations to use Route Reflector but I always finish in a routing loop. why are you establishing iBGP., that's exactly what I want to achieve (my final goal). This would achieve what you're looking for. One question, why are you establishing iBGP peering sessions with each one of your routers? Unless you use a Route Reflector, which I don't see you're using, you'll need a full mesh, and that's a pain the configure even for just a few routers.ġ.- Establish an iBGP session between your border routers (R0-OUT-01 and R0-OUT-02)Ģ.- Establish some sort of tunnel between them (GRE, IP-IP, etc.) the important part here, is that the tunnel must travel from your internal networkģ.- Add OSPF (why static routes? you're already using OSPF), include the tunnel's networks tooĤ.- Make R0-OUT-01 and R0-OUT-02 publish a default route, this way, your users will get to the internet over the nearest oneĥ.- In case there are some routes R0-OUT-01 doesn't know, but 02 does, it can send the traffic to it over the tunnelĦ.- In case R0-OUT-01 or 02 goes down, due to you publishing the default routes and using OSPF, the traffic would get re-routed to the nearest exit

If you need more information (which I think you need) let me know. I think I have a very issue with the understanding of RR!!! Third, I create a bgp peer R1-R2, R1-R3, R1-R5, R4-R3, R4-R2, R1-R5, R1-R6, R6-R5)Īfter that (I suppouse to propagate the prefix received from R0.) I've tried to set up client-to-client-reflection = yes (and no), and Route-reflector= yes (and no) but no matter what I do I always finish in a loop. I used OSPF to connect transit networks, then I establish a peer connection between every direct peer, R1-R2 but NEVER R1-R4. Second, I create a static route to reach every connected destination (R1-R2, R1-R3, R4-R3, R4-R2, R1-R5, R1-R6, R6-R5) I used 100.64.0.0/10 range to do that. The same situation happen with R1 and R2 or R1 and R3 of course R4 are connected to R3 and R2.įirst I set up a Loopback interface (bridge with mac) on every box and assign a /32. R1 and R5 are connected each other directly and through R6 as you can see. R0-OUT-02 is EQUAL to R0-OUT-01 with the same ASN for Internet and IXP but it is in another city. The first one, let's say ASN 10 is the Internet connection the second one, let's say ASN 20 is the IXP. I really don't know where is the problem.įirst of all, every link you see in the draw is a phisical link in FO or Wireless Link. I tried lots of configurations using RR but everytime I try a new configuration I finish in an eternal loop. It should be capable to self routing when a link becomes offline.

I have this situation, which is my real (i mean, physical) network structure and what I want to achieve is to establish a fully meshed network.
