Yes, you can.  Set atm clock internal on one router.  Forget LANE, it uses
SVCs.  For that you'll need a switch.

Hi all,
I have been ripping my hair out trying to bypass the password on this used
Bay Centillion I have and want to use as an ATM cloud. Since I cannot get
any support on it can I do a back to back PVC between 2 3640's with the ATM
OC3MM cards?

Thanks
Alan

First thoughts are a layer 3 issue.  If CDP is working and does see the
router at the other end and not some other router (have seen this when a
company is turning up multiple links between multiple sites, telco gets the
sites wrong and the connections aren't going where they should be) then we
know layer 2 is working.  It would be nice to have debugs from both sides
(pinger and pingee simultaneously) when doing a ping.  That may help.  I
have seen what at first appears to be a good setup give a sending going one
way and an "encapsulation failed" going the other.
Good Luck,

Steve

Hello, I need help in supposedly simplest configuration.

I have 2 sites connected via T1.


     R1<------------------>R2,
192.168.1.2           192.168.1.1

Where R1 has T1 and R2 has T1 channel in DS3. R1 - c2620. R2 - 7206vxr.I
have been doing similar scenario many many times and had no problem. This
time however I see both serials up/up but I can't ping. When I ping from
R2 to R1 this is what I got on R2:

15w3d: IP: s=192.168.1.1 (local), d=192.168.1.2 (Serial1/0/8:0), len 100,
sending.
15w3d: IP: s=192.168.1.1 (local), d=192.168.1.2 (Serial1/0/8:0), len 100,
sending.
15w3d: IP: s=192.168.1.1 (local), d=192.168.1.2 (Serial1/0/8:0), len 100,
sending.

When I ask to ping from R1 to R2 I see on R2:


15w3d: IP: s=192.168.1.2 (Serial1/0/8:0), d=192.168.1.1 (Serial1/0/8:0),
len 100, rcvd 3
15w3d: IP: s=192.168.1.1 (local), d=192.168.1.2 (Serial1/0/8:0), len 100,
sending
15w3d: IP: s=192.168.1.2 (Serial1/0/8:0), d=192.168.1.1 (Serial1/0/8:0),
len 100, rcvd 3
15w3d: IP: s=192.168.1.1 (local), d=192.168.1.2 (Serial1/0/8:0), len 100,
sending

But no success. On both interfaces - no errors at all. I can see the
routers through cdp. Encapsulation on both ends - hdlc. No access lists at
all, vanilla configuration.

I know you will ask details about the other end, but all it has is:

int se 0/0
ip address 192.168.1.2 255.255.255.0

I am afraid to get something like this on the lab. Aren't you ??
