I noticed a couple of problems in your configs. I suspect that some of it is a cut and paste error, and some of it is not. Here goes: 1. Both of your hostnames have a "-" character in them. Although there is nothing in the IOS that prohibits the use of a dash, I have always steered clear of dashes in usernames and hostnames. Some operating systems out there do not like dashes, but will accept an underscore "_". This is no big deal, but a good convention to follow. 2. On router 1 you have the following dialer map statement: dialer map ip 10.10.10.2 name 2600-1 Unfortunately, you did not append a phone number on the end of the dialer map statement. This router does not know what phone number to call to reach 10.10.10.2. Add the appropriate phone number and that problem should be fixed. 3. I assume you did a cut and paste error on router number 2. If not, I suspect that you prompt now looks something like this: 2600-1 password google# My recommendation would be to fix your host name with the following lines: 2600-1 password google(config)#hostname 2600-1 2600-1(config)# Then I would enter the correct username/password list: 2600-1(config)#user 3600-1 pass google 4. I would recommend the addition of the following line on each of the routers at interface config mode for bri0 for both: dialer-group 1 I would then add the following line to *global* config for both routers: dialer-list 1 protocol ip permit The first command listed above (dialer-group 1) binds the interface to the second command (dialer-list). The dilaer-list command will specify what is interesting traffic. That should be enough to get a working configuration, assuming you have already configured the proper ISDN switch type and SPIDs (if required). 5. The last thing I would do (possibly the first) is to read these links to understand exactly what I just said(watch wrap): http://www.cisco.com/univercd/cc/td/doc/cisintwk/idg4/nd2011.htm http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/c book/cddr.htm#xtocid2980814 HTH, Paul Werner > i am setting up an end-to-end isnd connection between two routers using > CHAP > athuentication.i seem to make a connection but cant ping even the local > side > the show ip route shows it as directly connected interface,when i do > show > int bri 0 i see (spoofing)what actually does it mean and how to get rid > of > it ??i have checked the configurations and searched on net a lot > configuration seems alright.if possible can someone send me a practical > working config (offcourse ips and passwords omitted).?? > > i realy would appreciate it.following is a general skecth just for > refernce. > > > following is the configuration > > Router 1: > > hostname 3600-1 > username 2600-1 password google > > int bri 0 > ip address 10.10.10.1 255.255.255.0 > encapsulation ppp > dialer map ip 10.10.10.2 name 2600-1 > ppp authentication chap > - ----- > > Router 2: > > hostname 2600-1 password google > > int bri 0 > ip address 10.10.10.2 255.255.255.0 > encapsulation ppp > dialer map ip 10.10.10.1 name 3600-1 1267126 > ppp authentication chap ________________________________________________ Get your own "800" number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
