Some of the good things are:

1. The Special Topics chapter that discusses the differences between IRB, CRB

and what BVI's are used for. Ive never found a better description.

2. The chapter on ATM/Frame Relay. I especially liked the definitions of ATM

encapsulation, aal5snap, aal5mux, aal5nlpid. Excellent. I liked the

discussion of LANE as well.

3. The line command chapter. Cleared up some things for me. Thanks.

A couple of the bad things are:

1. Mutlicasting should be better covered.

2. In the command reference It would be nice to know what IOS image the

command is supported in and on what platform.
