Connecting 2 Cisco Routers (back to back)
This is probably a real novice question but I'm trying to connect two
routers (2600's) back to back. Unfortunately I can't get them to see
each other. I've set them up each serial interface with an ip address
I've enabled the serial ports, set encapsulation to FRAME RELAY, lmi
The problem is that when I run: SHOW INT S0/0
I keep getting SERIAL UP, LINE PROTOCOL DOWN
I've notice when I do a SHOW FRAME-RELAY LMI it shows enquiries being
sent but not received.
Can anyone help me with this, i'm starting to get ...Connecting (2) WIC-1DSU-T1 WIC T1
If I add a WIC-1DSU-T1 WIC T1 to a 2650 router and another to a 3620 router
can I pin a cable to make a dte/dce connection to simulate a wan?

Yes. Google on 'Cross-over T1 cable'. There'll be a ton of hits.
You are beyond having a DTE or DCE once you have it encoded up to T1,
but having a point-to-point T1 that is 6" long works exactly just the
same as having a real...dual router back to back serial connection (2501 <-> 2620)
Thanks in advance.
Is it possible to run a back to back serial connection between a 2501
If so, what cabling would I require?
If not, is there an alternative configuration for the topology below,
or should I pickup another 2620?
Purpose: simulate a WAN connection between the two routers.
Reason: one router would be dhcp client for cable modem, WAN serial to
second router WAN serial, which acts as gateway for LAN.

Hello all. I want to find out if it is feasible and possble to set up a
backup connection to the Internet going through the T1 line between two
offices and through the other ISP connection.
This is my Network diagram :
ISP1 --------Office 1
---- : Fast Ethernet connection to ISP
|| : Frame Relay T1
I want to set it up so that if Office 1 loses Internet Connectivity the
traffic can go through the T1 to the Office 2 and then out to the
I have Cisco 1721 and 3620 routers connecting the two offices. And

The new ISR (1800, 2800, and 3800) routers will not work with the old
wic-1dsu-t1. You must use the new wic-1dsu-t1-v2.

I just put one in a 2801 and it detected it properly. I suppose you
could be saying it detects it but it does not function properly. I ask
because if it will not work then I need to purchase a proper card ASAP.

Or do you have to have the WIC-1DSU-T1-V2? Our current router uses the
non-V2 version and we want to know if we can bring those over or if we
need to order all new WICs.

I just bought a 2821 and replaced a 2600 and was in the same position,
the answer is no it will not take anything but a V2 WIC. It is a shame
because it...back to back routers
I am having a problem creating a mock frame relay connection between two
routers. Here is what i am trying to do:

| V.35 Serial Cable
| Ethernet to Hub
Here are my configs:
ip address 192.168.1.1 255.255.255.0

clock rate 64000

Router B...WIC-1DSU-T1 and WIC-1DSU-T1-V2
What is the difference between the two modules WIC-1DSU-T1 and
I need to connect two T1 lines for double bandwith and backup if one T1
fails. Do I have to get the V2 or any of them will do what I need ?
The WIC-1DSU-T1-V2 is an updated version of the WIC-1DSU-T1 interface
card (which has reached End-of-Life [EoL]/End-of-Sale [EoS]), that
offers additional supported features with the same performance:

I'm trying to connect two SHDSL routers, a Cisco 828 (IOS 12.3(6e)) and
a ZyXEL Prestige 791R. I have very limited experience with ATM, and
would appreciate any insight.
The physical interfaces go up on both sides, but I can't seem to get any
IP traffic through the VC.
This is what I've done on the Cisco side:
ip address 192.168.252.2 255.255.255.252
no atm ilmi-keepalive
