Learn how firewall policies control traffic across Juniper security zones, covering stateless and stateful firewalls, zone configuration, address books, and policy troubleshooting.
Explore configuring firewall policies on a Juniper S6 appliance by setting interfaces, security zones, address books, and application-based rules, then verify traffic with show security flow and policy statistics.
Explore IPsec components, protocols, and modes, including IKEv1/IKEv2, tunnel vs transport, and NAT traversal, to secure site-to-site and remote access connections with encrypted traffic.
Configure a route-based IPsec tunnel on a Juniper device and verify the IPsec security associations are up, then remove the traffic selectors and set up st0 and static routes.
Explore a three-router VRRP lab on Junos, set up g00 interfaces, the virtual IP 192.168.1.1, and router priorities; observe mastership failover and tie-breaking by priority and IP address.
Configure and verify BGP with external and internal sessions across a multi-site topology, leveraging OSPF learned loopbacks, route import/export policies, next-hop self, and community filtering for traffic engineering.
Explore how BGP confederations scale routes by combining iBGP and BGP with private subbase numbers, including route reflectors, loopback-based peering, and multipath configurations.
Hello,
I am delighted that you chose to attend this course. :)
As a Network Engineer, I started my Networking Career working on Juniper devices which made my transition and learning process so much smoother and faster. Why you may ask? Well let me explain to you:
- JunOS has an intuitive CLI, show commands and protocol configuration is pretty easy to understand.
- Documentation is short and on point most of the time.
- Configuration is easy to see and understand and it makes sense.
While creating this course, my focus was to show you the most used protocols and technologies in the actual working place, using as close to real-life scenarios as possible.
The focus of my lessons is the practice part, but you will find easy-to-understand lectures on how protocols and Juniper devices work, also I made sure to include topics that are liked by the interviewers when targeting a Network engineer role.
This course is targeted for beginner to intermediate level, the curriculum will take you slowly and will gradually increase its complexity, it is created in a way that you will immediately have to use the protocol/technology that we touched by assigning to you "homework" in form of practice labs after each Chapter and more complex multi-technology assignments once we learn more.
In my experience the best way to learn something is by practising it and playing with different scenarios it will for sure make you read more closely networking documentation and in return make you a better engineer.
What this course is proposing:
- Network and JunOS Fundamentals
- Firewall, Switch and Router handling
- LACP and MC-LAG
- Static routing and GRE Tunneling
- STP
- VRRP
- NAT
- OSPF, ISIS and BGP
- IPSec
Hop in and let's go!
Update 07/2024: BGP RouteReflectors, BGP Confederations, IPSec -> all with corresponding labs
