Administravia 20170703
Just a short note: I’ve updated the sixty book section of the site with a new plugin designed to keep track of book libraries. Along the way, I’ve added an Amazon affiliate code, so maybe I can buy a cup of hot chocolate and a piece of banana nut bread at some point in the future. 
The look should really be a bit nicer, though, and it is easier to add books to this system than manually adding them as I was doing before.
Remember that the idea of sixty books is not that there are actually 60 books on the list, but rather this is what I read in an average year—and hence what I am challenging you to work up to.

DMVPN Configurations on Juniper Router
Today I am going to talk about the configurations of DMVPN on Juniper routers and then associate Dynamic VPN with remote clients step by step. I talked about DMVPN earlier in my articles as well where i explained the basics of the DMVPN. I promised at that time that I will come up with the configurations of DMVPN on each and every vendor. Now I am coming up with the DMVPN configurations on Juniper routers first and I will come up with the configurations on Cisco, Huawei and HP routers later on.
Below are some of the links where i started with the DMVPN explanations

DMVPN Vs IPSEC Basics
Quick Comparison: IPSEC vs DMVPN vs EasyVPN vs GETVPN
The configurations used here are for the demo purposes and has no relevance with any of the live and the enterprise networks. What kind of Topology it looks like, So i am pasting here the sample DMVPN topology and has no relevance with the configuration defining below. The configuration is just for your reference to take it further.

ISIS Authentication types (packet captures)
In this post i would like to highlight a couple of “features” of ISIS.
More specifically the authentication mechanism used and how it looks in the data plane.
I will do this by configuring a couple of routers and configure the 2 authentication types available. I will then look at packet captures taken from the link between them and illustrate how its used by the ISIS process.
The 2 types of Authentication are link-level authentication of the Hello messages used to establish an adjacency and the second type is the authentication used to authenticate the LSP’s (Link State Packet) themselves.
First off, here is the extremely simple topology, but its all thats required for this purpose:
Simple, right? 2 routers with 1 link between them on Gig1. They are both running ISIS level-2-only mode, which means they will only try and establish a L2 adjacency with their neighbors. Each router has a loopback interface, which is also advertised into ISIS.
First off, lets look at the relevant configuration of CSR-02 for the Link-level authentication:
key chain MY-CHAIN key 1 key-string WIPPIE ! interface GigabitEthernet1 ip address 10.1.2.2 255.255.255.0 ip router isis 1 negotiation auto no Continue reading
Notes from IETF 99 – The IEPG Meeting
Interest in the DNS appears to come in pronounced surges. Its quiet for a few years, then there is a furious burst of activity. If the activity at the recent IETF meeting is any indication, we appear to be in the middle of a burst of activity.EVPN-VXLAN INTER-TENANT ROUTING ON JUNIPER QFX / MX
I’ve recently started working on a project focused on EVPN-VXLAN based on Juniper technology. I figured I’d take the opportunity to share some experiences specifically around inter-VXLAN routing. Inter-VXLAN routing can be useful when passing traffic between different tenants. For example, you may have a shared-services tenant that needs to be accessed by a number of different customer tenants whilst not allowing reachability between customer tenants. By enabling inter-VXLAN routing on the MX we can use various route-leaking techniques and policy to provide a technical point of control.

Notes from IETF 99 – The IEPG Meeting
Many years ago the IEPG had a role in allowing network operators to talk to other operators about what they were seeing and what they were thinking about. Those days are long since over, and today the IEPG meetings present an opportunity for an eclectic set of diehards to listen to an equally eclectic collection of presentations that wander over much of the topics of today's Internet, without any particular common theme or filter.2017 Edge Computing and MEC Report Survey is Here!

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
