CCIE Routing and Switching Practice Labs

Q: Are you asking me to configure "dialer-watch"?

A: To accomplish the requirement and make it stable, you need to decide what to configure.

Q: I cannot have any traffic at all passing through the ISDN link?

A: No. Traffic can only go through the ISDN link if R5 loses Fa0/0 interface connectivity.

Q: Should I configure any kind of authentication?

A: You are not required to do that. Sometimes you need a minimum configuration to have your basic ISDN working.
