I have 2 routers; a 1600 with a 10 base t ,an AUI, a 60 pin serial , and a
console port ,and a 2524 with a 10 base t , AUI, AUX, and a console port.

  Any suggestions as to the best way to connect them ,leaving me still with
a way of using the 10 base t ports ? ( I want to play with routing back to
the PC's after all)

  I could buy a serial WAN card on ebay for $60 and get a dce/dte cable. I
could buy  "Cisco RS232 DTE HDD60 to DB25 Male Cable" on ebay for much less
, and though the pins match what I have, I'm dubious as to it working .

 While I'm at this, here's another question based on  gross ignorance; do
the AUI ports "count" as another Ethernet device in the router,  or are they
simply another path, along with the 10base T , to eth0 ?

The AUI and 10baseT are two different ways of connecting to the same 
interface eth0.

If you connect the AUXes together, and the speed doesnt matter... I'm
curious if there are any limitations of IP traffic and routing
protocols. For example can you use the bandwidth command and alter
eigrp metrics of the aux port?

Sure, you can do that.

The OP's problem however is that he has a 1600 which doesn't HAVE an aux.

   Aaron, can I set up the aux on the 2524 to behave as ...how to say , an
ethernet port ?

Alas, the 1600 does not  have an AUX port.  There goes that idea.  But, 
you can connect the two with a DTE/DCE cable.  www.anthonypanda.com 
sells them cheap.

No.  The hardware driving the AUX port isn't an ethernet controller.

Yes, I understand the AUX port isn't an ethernet controller; I was wondering
if I can assign it an ip address (I see this can be done) and then configure
it in such a way that it could communicate with an ethernet device....
again, my ignorance here is profound .

No.  You use the AUX port to communicate with a serial line, and the 
Ethernet port to communicate with an Ethernet LAN.

In a round-about way yes.  You can use AUX port to create a ppp or slip 
connection.  Using a routing protocol, that subnet (used by ppp or slip) 
can be advertised to your other routers hanging off of the Ethernet 
side.

I strongly believed that the serial-aux method would work but had
never tried it.

The good news is that I have now.

It was a NIGHTMARE to get going.
My feeling is that unless you are very poor you would be 
better to go for your $60 serial card. With this I would
never be sure whether the weird async config was causing a 
problem or if it was something else. I am VERY pleased
that I had no modems in there!!!


You will need:
"Cisco RS232 DTE HDD60 to DB25 Male Cable" DTE
Cisco DB25 to RJ45 headshell ("Terminal" from console cablekit)
Cisco (Black/blue) rj45 to rj45 "rollover" cable

HDD60----------DB25|DB25-RJ45-----rollover-----RJ45


I had an 805 (Serial) and a 2600 (Aux)

For some reason the DTR signal on the Serial port did not come up.
I am not familiar enough with this stuff to work it out without a lot
Work.    "modem CTS-Alarm"   fixed that.

I seemed to get RIP working for a moment but it's gone for now.

"Sh line"   tells you what "line" is associated with the async interfaces.

As an aside:
I believe that the following is the case

DB25F(terminal)--straight--thro-------RJ45
   is the same as
DB25M(modem)-----rollover-------------RJ45

AND

DB25F(terminal)RJ45--rollover-------------RJ45
   is the same as
DB25M(modem)RJ45-----straight--thro-------RJ45


Finally two rollovers joined with a barrel connector produce a 
straight thru'.
This could be handy if one day you are stuck with one of the
new blue rollovers with moulded DB9 and you needed to unroll it.
