When trying to establish a ISDN DDR connection to 192.168.216.100 the connection is dialed sucessfully but when IP is assigned the connection is dropped.

All seams OK until the set_ip_peer output.
is this beace i'm using the Unnumbered IP for Dialer1 ?
The remote router is a BinTec ISDN router.

Probably. But there were no IPCP nego output from your debug.
Most implementations use the same network address between the two peers.
You can try using another ip address on the dialer interface belonging to the
same network as the remote peer.
Hope this helps.

! IP Static Routes
ip route 192.168.216.254 255.255.255.255 Dialer1
ip route 192.168.216.0 255.255.255.0 192.168.216.254
01-30-2003 03:32 PM
There is ip address mismatch here. Derbycimp wants to negotiate 192.168.216.254 ip address while DSSacdpsb wants to negotiate 192.168.211.254. Both the ip address are in two different networks. That is the problem on point to point link. You need to have both the peers on the same network/subnet.
So to make that work, you need to allocate the ip address of the ethernet interface on DSSacdpsb from 192.168.216.0 network. or use the different addressing scheme.
That way we will have both the peers in the same ip network..Once that changed you will be able to ping ecah other fine.

ip address 192.168.216.250 255.255.255.0

For wahtever reason this router got request to clear the connection..as we have received
00:16:52: BR0:1 LCP: I TERMREQ [Open] id 2 len 4
Now once this router rejects VJ compression, the other router should send CONFREG with just ip address as 192.168.216.254 but instead that router send TERMREQ..So i think you need to talk to other side router's admin about compressin issue..
You can configure "compress mppc" command under the bri0 interface and see if that makes any difference..Otherwise you need to talk to other side router's admin to sort that compression issue,
02-02-2003 12:39 PM
I've got details from the remote router admin
Encapsulation PPP
Compress STAC
Encryption MPPE 40
I assume that I need
Interface BRI0
compress STAC
but what IOS do I need from the Encryption type Mppe ?
Thanks
02-02-2003 03:58 PM
I think you are trying to replace the windows PC dialout to some server by 803 router..Looking on the previous debug you just need to have following to successfully negotiate the ip address between two routers.
Interface BRI0
compress STAC
Now if the remote side router is looking for Microsoft Point-to-Point Encryption (MPPE) 40 for data, you need images with IPSEC featureset in it. But 800 routers dosen't supports MPPE as per following url.

02-18-2003 08:14 AM
Thanks for your help removing MPPE 40 from teh remote router lets this config work!
Next question how dow I had a second Dialer ?
Dialer2
New IP Range 192.168.217.0
I'm confussed about the Dialer-Groups
02-18-2003 09:09 AM
Need to know why exactly you need the second dialer for. You can't add a second dialer interface using "dialer rotary-group x" one one physical bri interface. For that you need to have dialer-profiles" configured with one bri interface has a pool of two dialer interface. Here is the sample config for that
http://www.cisco.com/warp/public/793/access_dial/ddr_dialer_profile.html
OR
you can use another dialer-map in the same config.
02-18-2003 12:11 PM
I need to be able to Route to a different Remote Network.
by Dialer Map i assume you mean something like :-
dialer map snapshot 1 name Sealcimp broadcast 54321
dialer map ip 192.168.217.254 name Sealcimp speed 64 broadcast 54321
Can U point me in the direction of some "Dialer Map" info?
