Learning IOS and JUNOS

Junos Script Automation is a powerful and flexible on-box toolset which provides customization of network behavior, adaption to what your application expects to configure, manage and diagnose if and when needed. It sits right above the Junos OS, with a northbound interface to Junos Space applications, and southbound access to Junos SDK applications and native management plane instrumentation. This customized programmable solution makes your application smarter and better in real-time. In Juniper official website provides many script samples to match part of common requests. In my company, we deployed many inter-connections EBGP/IBGP between router or layer 3 switch. So I picked one op script from the JUNOS Script Library - show bgp policy : display all routing-policies in sequential order for a selected BGP peer.

Configuration Management Day 2 - How to review router configuration ? In Cisco IOS, it has two default configuration files:  (1) startup-config: is used for initialization of router boot up process   (2) running-config.  is the real-time concurrent configuration repository whenever you type any commands in IOS. And how do you differentiate screen output is the startup-config or running-config ?

Once a use, forever a custom My first-time experience of Cisco router installation was in 1997, when I was a junior network engineer in a small company. I remembered that day I finished installing a customer router on-site for only 15 mins then I left and went back again after 2 hours to configure the router via console again..because I forgot to configure password under line vty (I told myslef I would never made such stupid mistake again like that - Password required, but none set ) After 13 years later, I started to learn JUNOS since 2010. Because I familiar Cisco IOS so much, so I knew the feeling of use behavior change from IOS to JUNOS. The hierarchical structure is not so easy to read when you see it in the first time.(especially when you have no any programming experience) However, having the use experience of Cisco IOS is a not a bad thing before you start to learn JUNOS. I believe if you can leverage your previously IOS command knowledge then map to JUNOS relative state
