To eliminate this problem, we have to disable the “split horizon” function on Router 2’s Serial0/0/0, like this:

That is why Router 1 will not receive Router 3’s updates, because Router 2 won’t re-send them! Recall the default behaviour of “split horizon”: both Router 1 and Router 3 are addressed in the same subnet, so any EIGRP updates received in Router 2’s Serial0/0/0 interface connecting to this subnet will not be re-sent out through the same interface Serial0/0/0 by Router 2! Router 1 will never receive them unless Router 2 re-sends those EIGRP updates for Router 1. Therefore, only Router 2 will receive Router 3’s EIGRP updates. We have only two virtual circuits available in this case. If you investigate, then you will understand that the problem lies with Router2. Once you have completed the entire task, you can try the same scenario with EIGRP for better understanding.Īfter we start EIGRP on all routers with default setting, we will immediately see a serious problem: Router 1 does not receive Router 3’s EIGRP routes, and vice versa.

We must “disable” it on Routers Frame Relay interface Using “ip ospf network broadcast” Command or manual neighborship using “neighbor 10.1.1.X” under OSPF process.Īfter applying this you will realize that you have full mesh connectivity over all devices. The problem is “Non-Broadcast OSPF Network Type”. The frame relay access portion is actually done! Now we look closer at the OSPF problem.Īfter we start OSPF on all routers with default setting, we will immediately see a serious problem: Router 1 does not receive Router 3’s OSPF routes, and vice versa.

Here is the sample configuration for Router 1:Īfter you configure all three interfaces on three routers, please wait a moment! Cisco IOS’s Inverse ARP feature would automatically setup the correct IP addresses mapping to DLCIs.

All you have to do is to change serial encapsulation to “frame-relay”. The access to Frame Relay configuration is not difficult at all for you. We must “disable” it on Routers Frame Relay interface “ip ospf network broadcast” or manual neighborship using “neighbor 10.1.1.X” under OSPF process Key to the problem is “Non-Broadcast Network Type”. Use only 2 DLCIs: Router 1 to Router 2, and Router 2 to Router 3 and use OSPF only to complete full connectivity. No need to config Frame Relay Cloud & All IP address on hosts and Routers are preconfigured Configure OSPF for full connectivity between all hosts connected to Routers (you may face Non-Broadcast N/W Type issue so config ospf broadcast n/w type or you need to config Manual Neighbor-ship) Map 10.1.1.1 (Router1) to 10.1.1.3 (Router3) with Broadcast keyword so that you can Configure your WAN links with encapsulation frame-relay and with proper DLCIsĢ. This is a typical deployment in “hub and spoke” scenario to minimize virtual circuit cost!ġ. One is between Router 1 and Router 2, and the other is between Router 2 and Router 3.

If you check the frame relay scenario in packet tracer, you will find that we have two Virtual Circuits available.
