ISDN Connection issue between 2 801 routers

[ajordan0]

Hi all

I am having problems with 2 801 routers that I have configured for ddr from router1 to router2.

Router1 will dial to Router2 but no traffic will flow.

I have included configs for both, please help if you can!!

Thanx

Just make sure that the dialer map statement o router R2 have exact hostname of the router R1. As per the config you have Oli** as the host name of R1 but in the dialer map on R2, you have name as Oliv** . So be sure on that.

If that is fine then you might need to remove the "snampshot" config just for testing. If still no routing after connection, need to see what "debug ip icmp" reports when you issue ping from R1 to R2. Lets see if anything may have went wrong during PPP. So pl. enable debug for following

debug isdn q931

debug ppp nego

debug dialer

Collect that debug on R2 (receiving router) Also include sh ip route as well.

I can ping the welli* router and the dialer using the router interface, I can also ping the Welli* interface (192.168.3.7 & 192.168.0.23), but can't get any further.

Also using a command prompt with a default gateway of 192.168.2.2, traffic goes out but the pings fail.

Thanks for all of your help.
