About

Harris AndreaWelcome to my corner on the web. My name is Harris Andrea and I’m a security and network engineer working in an Internet Service Provider.

The main purpose of this blog is to provide technical tutorials, configuration examples and guides about IP networks with focus on Cisco products and technologies. I believe that the resources offered here can be useful for a range of professionals (beginners to experts) working with Cisco products, from routing and switching to security and IP Telephony.

I have been working with Cisco products for around two decades. To support my knowledge and build a strong professional background, I have also studied and earned several Cisco Certifications such as CCNA, CCNP, and CCSP. I decided to build this blog in order to record down and share some of my knowledge and experience acquired over the years in the networking field.

As a network and security engineer of IP networks, I came across various technologies implemented in the networks I work. Some examples include different routing protocols (OSPF, BGP, ISIS), MPLS technologies (Layer 2 and Layer 3 VPNs), security technologies (ASA Firewalls, IPSEC VPNs, encryption, IPS systems), Voice over IP, Quality of service, wireless technologies etc.

I’m also the author of two Cisco books which have been embraced by thousands of Cisco professionals:
