But today I want to add some more fun here for you guys. So here is a great frame-relay challenge for you guys which I solved recently sent by one friend. And of-course this scenario got so much to teach you and test your frame-relay skills. To solve this scenario you would need to recall all frame relay basics. At-least that's what I feel honestly.
One last thing as surprise package is - the first guy who will post the correct solution as per requirements will get a surprise CCIE R&S preparation material from me in free. :-)
I'll wait till 5 PM IST Monday evening before I post the correct solution here. So good luck as you have plenty of time for such small but still interesting task to be solved & have a nice weekend ahead.
Here are the quick requirements with Detailed Diagram.
2.> Don't use subinterfaces on R1, R2 & R3
3.> Use Sub-interface on .1 on R4 eg - s0/0.1
4.> Don't use any dynamic Frame-Relay mappings anywhere
5.> Don't use any Static Frame-Relay mappings on R4
6.> Traffic From R2 destined for R4 should transit R1
7.> All other traffic should take the most direct path through Frame-Relay network
Note:- No Extra Configs should be put unless otherwise specified, all router should have full reach-ability (including self interfaces), no redundant broadcast should be occurring on any of DLCIs.
