If we're exploring all of the possible ways to do a back-to-back
frame-relay connection, we could also include the following (which
allows two ends of a connection to share the same DLCI)
On the DCE router: (sh controller serial x)
Frame-relay switching
Interface serial x/y/z
Ip address A.B.C.D
Encapsulation frame-relay
Frame-relay intf-type dce
Clockrate 64000
Frame-relay interface-dlci xxxx
<insert frame relay specific configuration here>
On the DTE router:
Interface serial x/y/z
Ip address A.B.C.D.
Encapsulation frame-relay
<insert frame relay specific configuration here>

Dave, I think that you need the outgoing interface in the Serial 1/2,
Something like .. frame-relay route 121 interface Serial1/1 102
Schulz, Dave escribis:
So, if I may summarize (please let me know if I have this right).... to
run frame-relay (L3) over the router on a point-to-point.....you have
two
ways to accomplish this.... With LMI enabled..... interface Serial1/2
ip address 10.1.1.3 255.255.255.0
encapsulation frame-relay
clockrate 64000
frame-relay map ip 10.1.1.1 131 broadcast frame-relay intf-type dce
frame-relay route 121 or with no LMI..... interface Serial1/2
ip address 10.1.1.3 255.255.255.0 no keepalive
encapsulation frame-relay
clockrate 64000
frame-relay map ip 10.1.1.1 131 broadcast Correct?

Allow me to pull some teeth and split some hairs here... (or is it
split
teeth and pull hairs?)
For a >>particular DLCI<<, you are either in L2 mode or in L3 mode. As
you
demonstrated, yes, things can go either way, but when you look at any
ONE
DLCI you make a choice.
And I only figured that I needed to be THAT specific on my wording when
I
was either running for political office or talking to my daughter.
Now where was that original question going anyway? I'm sure it was
leading
towards BGP not working right. Or telnet, yeah, musta been telnet.
But yes, in order to increase the chances for a date, you can go both
ways.
L2 or L3. Just not both on the same interface for the same DLCI. But
you
still need to make some choice as to which way you're going, otherwise
the
evening will become very confusing.

If you don't issue and "frame-relay route" commands, then you can still
participate in the frame-relay directly. As soon as you choose to set
up
L2 virtual circuits though, you are correct Dave in that you are no
longer
playing at Layer 3.

Dave, I had the same misconcept, but my FRSW is working like a normal
router
running OSPF / BGP / Mcast ...
