Working from the my last couple of EIGRP posts I am going to try and crystallize some of the material found by working through questions found in Stewart, B,D., Gough, C (2008). CCNP BSCI Official Exam Certification Guide, Fourth Edition. Indianapolis: Cisco Press.

If a multipoint serial interface uses five Permanent Virtual Circuits (PVCs) with Committed Information Rates (CIRs) of 56-, 128-, 128-, 128-, and 256-kbps, how would the bandwidth command be implemented on the interface?

EIGRP will assume even distribution of bandwidth on a multipoint interface. The bandwidth command serves two purposes in this situation,

IOS uses it as part of the routing metric and determines how much traffic it can send over an interface

One method method is to take the slowest PVC and calculate aggregate bandwidth

A better solution would be to split the PVC into subinterfaces so that each subinterfaces can be treated on its own.

Notes and Notices:

This is a part of my personal BSCI notes and research to assist myself in learning and understanding the concepts and theory for the BSCI exam. I learn by making notes reading and writing things down and wish to file them where I can’t lose them. These notes are not to be seen, judged or mistaken for replacements to Cisco recognized and authorized training which I personally support and attend and suggest you undertake if you are going for the BSCI Certification.
