What you describe is pretty much what I have setup, other than we don't
have a PM product on the other end (I forget what it is). I've used a
spare subnet from a Class C I have subnetted into 16 IP blocks for the WAN
network.

I'm still not quite clear on which DLCI I should be putting into my config.
When putting the PM into config mode (as shown in
http://www.livingston.com/Tech/Appnotes/app.wan-frame-relay.shtml), I can
see that the Full Status Report from the Telco switch reports DLCI 151:

(W1) Annex-D: Sending Full Status Enquiry - Sequence 8
(W1) LMI-AnnexD: Received Full Status - Sequence 7
DLCI List: 151

(I've tried both Annex-D and LMI signalling BTW)

But it doesn't seem to learn an IP to go with it if I don't specify one as
the manual seems to indicate it should.

pm2> sh arp frmW1
0.0.0.0 at 24:71 (151) <-- Any idea what the 24:71 means?

So does DLCI: 151 go into my DLCI list, or do I put the other DLCI (in this
case 171) into my list, with the IP address of the other end?
