I've been trying connecting two routers via AUX ports as described in the document http://www.cisco.com/warp/public/793/access_dial/auxback.html. Connection is OK but dynamic routing protocols don't work. I tried EIGRP and RIP. With EIGRP I see that no neighborhood. What may be the problem?
Configurations:
router1:
--------------
interface Async4
ip address 10.1.2.1 255.255.255.252
no ip mroute-cache
encapsulation ppp
no ip route-cache
async dynamic routing
async mode dedicated
router eigrp 1
network 10.0.0.0
------------------------------------------------
router2:
---------
interface Async9
ip address 10.1.2.2 255.255.255.252
encapsulation ppp
async dynamic routing
async mode dedicated
router eigrp 1
network 10.0.0.0

Can you ping from one router to other through the async interface ?

First, Try to configure "async default routing" instead of "async dynamic routing". Since you have tried many routing protocols, here is the working config using OSPF,
http://www.cisco.com/warp/public/793/access_dial/multilink_2serial_async.html
Just to add, if yo can't ping once the connection is made, we need to troubleshoot that first.
If you can ping, then we need see "show ip eigrp interface" and verify that the async interface is included for eigrp or not..(it should based on ip address)
After that need to debug for "debug ip eigrp" to see the eigrp related activities.

Yes, I changed the "async dynamic routing" line with "async default routing" and it worked. I read command reference docs on these commands but I couldn't see a difference, what's the point here?
Thanks to everyone involved.

This info might help:
[async dynamic routing]
A remote user who establishes a PPP or SLIP connection to this
asynchronous interface can enable routing by using the /routing
switch or the ppp/routing command. However, if you want to establish
routing by default on connections to an asynchronous interface,
use the async default routing command when you configure the interface.
You can compare this with the "async dynamic address" command under
the async interface configuration wherein the dialing side defines
the ip address that it will use, instead of the router assigning the
ip address.

Thanks a lot.

Yes, I can.
