JUNIPER NORTHSTAR UPGRADE 2.1 TO 3.0
In this post, I’m quickly going to describe how to upgrade NorthStar 2.1 to 3.0. For a detailed installation and user guide refer to the 3.0 release notes here.
Firstly, let’s start off by verifying the current host OS and NorthStar versions. Note. NorthStar 3.0 requires a minimum of Centos 6.7 or above.
[root@northstar ~]# cat /etc/redhat-release
CentOS release 6.9 (Final)
To check the current version of NorthStar, navigate to the about section via the drop down menu located at the top right of the GUI
Download NorthStar, Extract & Copy:
Download the NorthStar 3.0 application from Juniper.net NorthStar download page. Once downloaded, extract the RPM and copy to your host machine. Below I have copied the NorthStar-Bundle-3.0.0-20170630_141113_70366_586.x86_64.rpm to the /root/rpms/ directory.
[root@northstar ~]# ls /root/rpms/ -l
total 3843976

Context From The People
Are you ready for the flood of context-based networking solutions? If not, it’s time to invest in sandbags. After the launch of Cisco’s Intuitive Network solution set at Cisco Live, the rest of the context solutions are coming out to play. Granted, some of them are like Apstra and have been doing this for a while. Others are going to be jumping on the bandwagon of providing a solution that helps with context. But why are we here and why now?
Creating Context
The truth is that we’ve had context in the network for decades now. It’s not a part number that we can order from a vendor. It’s not a command that we type into the CLI to activate. In fact, it’s nothing that you can see at all right now, unless there’s a mirror handy.
The context in networks has been provided by people for as far back as anyone can remember. You do it every day without consciously realizing it. You interpret error messages and disregard those that aren’t important. People know how to program VLANs correctly to segment traffic in certain ways. Security context, application context, and more are delivered by breathing, thinking humans.

OSPF Show Commands : Cisco, Juniper, Huawei, HP and Arista Networks
I am going to talk about the OSPF show commands in this article on different vendors which includes Cisco, Juniper, Huawei, HP and Arista Networks. These commands are working as per the device you have. Please let me know if you knew any other commands in general for OSPF in different platforms which includes Cisco, Juniper, Huawei, HP and Arista Networks.
Above is the sample topology and below are the sample OSPF show commands which will help you to troubleshoot OSPF in your network for the various platforms

How to use Cloudflare for Service Discovery
Cloudflare runs 3,588 containers, making up 1,264 apps and services that all need to be able to find and discover each other in order to communicate -- a problem solved with service discovery.
You can use Cloudflare for service discovery. By deploying microservices behind Cloudflare, microservices’ origins are masked, secured from DDoS and L7 exploits and authenticated, and service discovery is natively built in. Cloudflare is also cloud platform agnostic, which means that if you have distributed infrastructure deployed across cloud platforms, you still get a holistic view of your services and the ability to manage your security and authentication policies in one place, independent of where services are actually deployed.
How it works
Service locations and metadata are stored in a distributed KV store deployed in all 100+ Cloudflare edge locations (the service registry).
Services register themselves to the service registry when they start up and deregister themselves when they spin down via a POST to Cloudflare’s API. Services provide data in the form of a DNS record, either by giving Cloudflare the address of the service in an A (IPv4) or AAAA (IPv6) record, or by providing more metadata like transport protocol and port in an SRV record.
Configuring Private VLANs on Juniper Switches
Thanks for the huge support on all my previous articles. Today I am going to talk about the Private VLANs configuration on the Juniper Switches. Earlier I wrote a article where i talk about the basics of the Private VLANs and the vendors supported to Private VLANs. If you want to have a look on that article, please go through the below mentioned link for the Private VLANs
Basics of Private VLANs
I am sure after reading the above article you will come to know about the basics of the Private VLANs. In this article I am going to cover the Configurational part of the Private VLANs on Juniper Switches, as it is demanded by some of the candidates on the blogs.
I will soon come up the configuration and the topology for the Private VLANs on Cisco and Huawei as well in another article.
A lot of people asking me about the VLANs, before starting with the configuration of the Private VLANs, let me quickly go through the VLANs and Private VLANs.

VMware vSphere vSwitches
Local and Distributed vSwitches server the same purpose as physical switches allowing for VM vNICs to be assigned to specific VLANs. In a production environment it is usual to define a local vSwitch on each ESX host for management and backdoor and have distributed vSwitches shared between hosts for VMs.
Cisco N1000v Switches
A cisco vswitch that can be used instead of the default VMware DvS to have a similar environment to that of Cisco physical NXOS switches. The control and packet communication can either be carried over VLANs in Layer2 mode or IP addresses in Layer3 mode. The default and Cisco recommended solution is L3 mode.
