Each PVC is treated separately. So your "full mesh" indicates a number of
pvc's between each router.

As an example, here's what we use in basic pod setup:

frame-relay switching
!
!
!
interface Serial0
 description Connection to R2 INT S0/1/0
 no ip address
 encapsulation frame-relay
 no ip mroute-cache
 no fair-queue
 clockrate 4000000
 frame-relay intf-type dce
 frame-relay route 204 interface Serial1 402
 frame-relay route 205 interface Serial2 502
 frame-relay route 206 interface Serial3 602
 no shut
!
interface Serial1
 description Connection to R4 INT s0/0/0
 no ip address
 encapsulation frame-relay
 clockrate 4000000
 frame-relay intf-type dce
 frame-relay route 402 interface Serial0 204
 frame-relay route 405 interface Serial2 504
 frame-relay route 406 interface Serial3 604
 no shut
!
interface Serial2
 description Connection to R5 int S0/1/0
 no ip address
 encapsulation frame-relay
 clockrate 115200
 frame-relay intf-type dce
 frame-relay route 502 interface Serial0 205
 frame-relay route 504 interface Serial1 405
 frame-relay route 506 interface Serial3 605
 no shut
!
interface Serial3
 description Connection to R6 Int S4/0
 no ip address
 encapsulation frame-relay
 clockrate 115200
 frame-relay intf-type dce
 frame-relay route 602 interface Serial0 206
 frame-relay route 604 interface Serial1 406
 frame-relay route 605 interface Serial2 506
 no shut

So by creating multiple entries there, you are drawing out each PVC. Sit
down with this, and some paper and starting drawing lines. Soon, as you go
through the commands, the building will make sense.

Remember that each line describes one-way communications.

David,

This only really shows a point to point setup, my confusion is on Multipoint
- Fully meshed design. Because the local input DLCI# commands cannot be
repeated, I am confused on how to set this up and how it works.

Any insight you may have on this would be helpful.

Thanks.

Hi,

You might look at this link:

uration_example09186a0080094a3c.shtml

I think it will get you started in the right direction....
