I would suggest that you do not use IP Unnumbered on the Virtual Templates,
instead configure them with an IP address directly
When you try and ping these addresses they will not resolve to the VT's but
to the subinterfaces, this will cause a problem

Subject: Frame-Relay PPP issues? Help would be great!
I'm working on frame PPP that looks like this-
R5----FR----R1
|
FR
|
R2------PPP/FR-----R3
R5-R2-R1 are in OSPF area 0 - with R5 as the DR
R2 and R3 are in OSPF area 1
I can see the routes on all routers but can not ping or telnet to R3 from R5
or R1
R2 has full reachablity -
From R5, I can ping the outgoing interface on R2 towards R3
When i trace from R5 to R3 the trace stops at R2
I know it has to be a problem with my ppp config because if i go back just
the point-to-point interface everything works fine.
I'm sure this must be something simple that I'm doing wrong...I have been
messing with it for a couple of hours and can't get anywhere.
Can anyone help me with this ppp config?
Is it possible I'm having problems with my FR switch?
Thanks
Justin Wireman
