This is a Lab Challenge only for EIGRP, based on the request from one of the users at the networking-forum.com. The base configuration is not too complex and is limited to five routers but it got some nice stuff to look after. I hope you enjoy it 🙂
If you want to do the lab and got questions, just drop me a line.
As with the other Lab in the end you have to have full connectivity between all routers and their interfaces.
Configure your lab according to the diagram (click on the picture to see it full size)
Configure Frame-Relay as shown in the diagram, only use the physical Interfaces.
Configure all interfaces into EIGRP AS100
Configure unicast neighborships between: R3 <-> R4 and R3<->R5. R4 and R5 should not form a neighborship. R4 and R5 should still have each others loopback interface in their routing table.
Configure Default Routing on R2, use a ip summary-address and assure that all routers in the domain have the default route to R2. Also be sure that every router still has R2s loopback 0 address in its routing table.
Configure R1 so that it uses a 3:1 load sharing for R2s loopback network 220.127.116.11/24 over its two interfaces to R3. Do not use the bandwidth command.
Configure an adjacency authentication between R1 and R3 on their Ethernet connection.
