Introduction to Filter list for JUNOS

Sunday, June 14th, 2009

Junipers JUNOS is a very robust operating system, not only is the OS very advanced but the ASIC heavy design of Juniper hardware is akin to calorie free chocolate bars! Juniper Filter Lists which are non-stateful packet filters similar to Cisco Access-Lists are compiled and processed using hardware, what this means is that you can have as many Filter-Lists as you want and as long as you want without degrading performance.

Juniper is also big on naming things, in JUNOS everything has a name, the Filter Lists have names, the terms in the Filter Lists have names, and even the address’s you are matching on have names. This is a big concept in JUNOS because it allows you to write snippets of Filter-Lists and use them for many different Filter Lists. JUNOS also supports grouping Filter Lists and applying an entire group of filter to an interface. If you apply Filter groups to a JUNOS interface they individual Filter Lists are evaluated in order sequentially.

Once the system was built and installed I had allot of fun setting up classic door games such as Trade wars and others.
