Frame relay - first stumbling block

Hi all,

I am a complete newbie to Cisco and CCNA. I work as a network administrator so I have a decent base knowledge of networking concepts but I am struggling massively with the actual configuration of routers in a frame relay.

I understand that i need to set the encapsulation, interface and lmi type for each router as well as the dlci numbers for the PVC to the destination router but I can not get a functioning network i.e. I can not get one of the routers to successfully ping another router on the opposite side of the cloud.

I think I have fallen into the trap of a lot of newcomers into the cisco/world in that the theory is easier to digest than the actual practicality: I understand what is supposed to be happening but I just cant get it to happen!!!

I would greatly appreciate any help - not necessarily an answer as I really want to solve this little problem by myself but pointers in the right direction would be fabulous.

Aside from this stumbling block I am really enjoying my studies so far.

Look forward to hearing from you.

Thanks

PS this is not a physical lab but simulated on Packet Tracer.

Post your config.
Are you using inverse arp or are you statically mapping the dlci's?

do you have a frame-relay switch in between...

so the config of the two DTE's and the Frame-relay switch

I now realise the error of my ways!!! No wonder there is nothing happening....I have not configured inverse arp.

I do have the frame relay switch between the DTEs but I have not enabled inverse arp - hopefully this will work.

I'll be back

Thank you very much

Hi guys - I actually removed the frame relay switch between the dce and dte and issued the "no keepalive" command on serial interfaces of all routers and this has allowed connectivity.

I wonder if you could shed some light on the pros/cons of this method i.e. would the implementation of frame-relay switch have been a more suitable path.

Thanks for your help

P.S. This is the first time I have posted in a CCNA forum so thanks for making me feel welcome with the swift responses - much appreciated
