  Sybex 5th Ed (pg 547) indicates that you can run frame-relay back-to-back using the following example...
  

  RouterA
  
  interface Serial0/0
   ip address 192.168.99.1 255.255.255.252
   no ip directed-broadcast
   encapsulation frame-relay
   clockrate 64000
   frame-relay interface-dlci 100
   frame-relay lmi-type ansi
  
  RouterB
  
  interface Serial0/0
   ip address 192.168.99.2 255.255.255.252
   no ip directed-broadcast
   encapsulation frame-relay
   frame-relay interface-dlci 100
   frame-relay lmi-type ansi
  

  
  
  However, the connection doesn't come up using this setup (line up, protocol down)...should this config have actually worked?
  
  I did some research and found the below config which worked...apparently you have to disable LMI's on the serial interface with the 'no keepalive' command...
  

  Router A
  
  interface Serial0/0
   no ip address
   no ip directed-broadcast
   encapsulation frame-relay
   no keepalive
   clockrate 64000
  !
  interface Serial0/0.1 point-to-point
   ip address 192.168.99.1 255.255.255.252
   no ip directed-broadcast
   frame-relay interface-dlci 100   
  
  Router B
  
  interface Serial0/0
   no ip address
   no ip directed-broadcast
   encapsulation frame-relay
   no keepalive
  !
  interface Serial0/0.1 point-to-point
   ip address 192.168.99.2 255.255.255.252
   no ip directed-broadcast
   frame-relay interface-dlci 100   
  

  
  r_durant,
  
  Do you have a frame relay switch?

  Ya the no keepalive is the workaround for not having a frame-relay switch.

  There is no place like 127.0.0.1 BUT 209.62.5.3 is my 127.0.0.1 away from 127.0.0.1!
