Two frame-relay switches connected together nni

Hello,

I'm trying to build a setup for a testnetwork, I got two identical setups (racks) with 8 routers.

Between those two racks I got got two frame-relay switches which are also connected together.

Now the local pvc do work for example router 8 in rack 1 to router 2 in rack one will have a dlci of 812 and 218.

Now I want also to be able to create a full mesh between all 16 routers, so I was thinking nni....

Let's say I got router 8 in Rack one and router 5 in rack two.. So My config would look like this

!

R8-1

!

!

interface Serial0/0/0

description ;LINK TO FR CLOUD

no ip address

encapsulation frame-relay

no ip mroute-cache

no fair-queue

clock rate 2000000

frame-relay lmi-type cisco

end

!

interface Serial0/0/0.825 point-to-point

description ;LINK TO R5 (RACK #2)

no ip mroute-cache

frame-relay interface-dlci 825

FS1-1

interface Serial2/0

description :LINK TO R8 S0/0/0 (RACK #1)

frame-relay route 825 interface Serial0/0 508

interface Serial0/0/0

no ip mroute-cache

end

interface Serial0/0/0.518 point-to-point

frame-relay interface-dlci 518

Now both pvc will stay in "inactive".. when I do a debug of frame-relay switching on the fram-relay switches It will show "active"...

Does anyone know what I'm doing wrong...

Ps: the subinterface is also down/down..

PS: routers are 2821's and fr switches are 3640's.

Please check below link :

You have to enable "frame-relay switching", "frame-realy route" for the DLCI that which PVC connect to which interface and frame-relay DCE interface because you are using back-to-back connect, one side will be DCE interace.

Please advise if there is any problem.

Hope this helps.
