Direct Interconnecting Cisco Asyc

Hi all,

I've got two Cisco AS2511-RJ (16 Async Ports, amongst others).

Just for the hell of it, I want to configure the routers with a direct
(crossover) link between an Asynch port on each router, similar to
using a DTE-DCE crossover cable on synchronous ports.

I can find lots and lots of infor on configuring modems, PPP, etc. but
little on doing a lab environment direct crossover.

Any ideas? Otherwise I guess I gotta break out a couple of modems and
a PABX to fake the WAN Dial-up connection....

Thanks

 

use the console cable

router 1
Interface Async 65
ip address 192.168.1.1 255.255.255.0
encapsulation ppp
async default routing
async dynamic routing
async mode dedicated


router 2
Interface Async 65
ip address 192.168.1.2 255.255.255.0
encapsulation ppp
async default routing
async dynamic routing
async mode dedicated

 

for testing or maybe router access for admin but I would not use the built
in AUX port for real data if much.

The built in AUX port can use a lot of CPU, Interupt heavy. However
dedicated ASYNC modules are designed to offload the interupt traffic from
the CPU.
