    1. About Juniper Routers

    Main products offered by Juniper include T-Series, M-Series, E-Series, MX-Series, J-Series routers,EX-Series Ethernet switches and SRX-Series Security products. JUN S is the operatin! syste" thatruns on "ost of the #uniper$s networ%in! e&uip"ent.

    . C!"ssi#i$"tion o# Juniper Routers:

    The routers are classified in to M-series, J-series, T-series, E-series, and MX-series based on thefunctionality. So"e fre&uently used "odels are !i'en below(
