Bruce Caslow said several times "ISDN is a CCIE killer" so I am going to
kill it before it kills me (in the lab)! I am currently working on a
scenario that uses ISDN dialer profiles, PPP authentication and is
implementing PPP callback. I am a little curious though of the proper
placement of commands. I don't want the proctors to have any reason to fail
me, so I want to try to cut down on the unneeded commands.
A couple of questions for the dialer masters out there:
Do you need to have the commands "ppp callback request" "ppp callback
accept" and (if you were going to bond the b-channels)"ppp multilink" on
both the physical BRI line and the Dialer interface?
Do you need to have "dialer-group _" on the callback router?
I've also included my configs if anyone would like to tear them apart to
tell me what is wrong with my dialer configurations if they see any. Cause I
know everyone here loves to read through Cisco configs!
Thanks in advance as always!!!
