Question

Posted

Can anyone recommend me any good Juniper (Network) Blogs to read, Any good articles, Cheat sheets? Anything at all? I might be up for a job which is more Juniper based than Cisco. I know my way around stuff but I would just like to brush up and get familiar with any Juniper Quirks that may crop up. Usually alot of people write blogs for Cisco and their CCIE Mission, Any Similar for Juniper?

Hey Chuck, I've worked with a lot of Juniper equipment myself, although not so much any more. I used to frequently set-up and configure the big 960's. I remember being introduced on them with some CCNA style slides/presentation material which helps you understand the concepts of JunOS in comparison to IOS. I'll try dig them out. The only thing I can say is that its very layer based and feels way more organised as a routing OS than IOS. Once you get used to it, you'll probably hate working with Cisco kit.

I think its paid material actually what got purchased for me while I was taking my JCNA. The only stuff I can find is a bunch of PDF's which go into example configurations which are found here:
http://www.juniper.net/techpubs/en_US/release-independent/nce/information-products/pathway-pages/nce/index.html

 

If you dump a whole configuration, its in a tabular format, and in JunOS you'd literally use the command "set" in that same format. So for example, to set an IP address to an interface it would be:

set interface ge-0/0/1 unit 0 family inet address 10.0.0.1/30

In the configuration that would be shown as:

interface {
      ge-0/0/1 {
            unit 0 {
                    family inet {
                          address 10.0.0.1/30;
                   }
           }
     }
}

See how the command literally mimics the structure of it? So you use the "set" command and write it in the form of each layer if you see what I mean? You also can select into layers and use wildcards like in UNIX. JunOS also works with commits and saves. You also can restore previous configurations and such.

 

Hope that helps a little. 

 

EDIT: If you have a bit of time and an absolute power house of a PC, set up GNS 3 and use some JunOS images and have a play. Really good router topology software if you've never used it.
