sorry for the late reply..

But are you using 'enterprise' code on both ends? Otherwise this will not work.

thanks

Subject: Using Two 2500 Routers as Frame Switch

I tried making a frame switching using two 2500 routers connect via AUX =
ports. I put IP addresses on the async interface, used PPP =
encapsulation and CHAP authentication. I set the transmit and receive =
speed on the AUX port to 38,400. I created a tunnel interface to go =
from the local async interface to the remote router and vice versa. I =
then continued with the regular config for a frame switch. Enabling =
"frame switching", specifying the "intf-type dce", using the "frame =
route" command but attempted to use the Tunnel interface instead of the =
Serial interface as per instructions in Rudenko's "Little Black Book". =
Doesn't work. I can't put the tunnel interface in, in place of the =
serial interface. What gives? I'm running 12.0 code and I'm using the =
rollover console cable between boxes. I have no idea why DLCI 421 and =
423 are being used either. Here is the config from Rudenko's "Little =
Black Book":

                                     R2
                                    (s0) dlci 201 to R1, dlci 203 to R3
                                      |
                                    (s0)
                                    FR2
                                 (a1)
                                   /
                                 (a1)=20
                                 FR1
       dlci 102 to R2 (s0) (s1) dlci 302 to R2
                               | \
                             (s0) (s0)
                             R1 R3
