Hi All,
I hope someone can shed some light on the problem I have come across in the
following scenario :

router in the middle doing frame relay switching. The frame switch is _not_
fully meshed. R1 is acting as the hub w
Your telco provisioned the PVC on the same circuit as DLCI 17, this is
evident by the show frame-relay pvc command. You have it configured on
Serial 0, which is why it shows up, down. But it is actually on Serial 1.
Try configuring the sub-interface on Serial 1, and I bet it comes up and
starts

If you could post the configs it would help, but here's some ideas to try.
Are you sure have inverse ARP working?
Have you tried a static route to R3 (from R2) gatewayed to R1's IP and the

Look into Proxy ARP.

Hence the problem.

This sounds like your router misses LMI status messages every once and a
while. This could mean a timer problem or the serial interface
could be too busy to process them correctly. My guess is the timer problem,

It is my understanding that on point-to-point
interfaces they need to be on seperate subnets. If
you have multiple routers coming into one interface,
declare the interface a point-to-multipoint interface.
Do this when you create the subinterface or use the
"ip ospf network X" interface comma
relay to each
other.

Make sure you have 'ip bootp server' configured (default), and not 'no ip
bootp server'. It will stop the ip helper-address from forwarding DHCP
requests if you have it disabled.

site with DHCP problems.
