How to Control IGP Updates with Route Maps and Distribute Lists

Article | May 09, 2017

The purpose of Interior Routing Protocols (IGP), and routing protocols more generally, is to advertise the existence of destination networks. All protocols then have some method of picking what they would consider to be the best path and maintain the information. By...

A Guide to Network Time Protocol (NTP)

Article | May 03, 2017

What is Network Time Protocol (NTP)? Well, it’s a network protocol used to synchronize clocks between computing systems over a packet switched network. It’s been around since the mid-1980s and was developed by David Mills at the University of Delaware; it is one of the oldest protocols still around on the Internet. NTP replaced other time synchronization technologies that didn’t have some capabilities to adjust time based on location of the time source or time server relative to the receiver or adjusting to the variation of delay found on typical data networks.

How Precision Time Protocol (PTP) is Improving Accuracy One Clock at a Time

Article | April 27, 2017

Precision Time Protocol (PTP) is a protocol designed to go beyond what Network Time Protocol (NTP) can offer relative to accuracy. PTP is IEEE standard 1588 that can give local computing systems accuracy within the sub-microsecond range (such as microsecond, nanosecond or picoseconds) whereas NTP is within milliseconds or longer. PTP standard was first released in 2002 and known as 1588-2002. In 2008, the IEEE released a revised standard for PTP, known as 1588-2008, that improved the accuracy and precision of the protocol. It is also known as PTPv2 and is not backward compatible with the older version. PTP was developed for packet based network for control and measurement systems.

How to Reach Devices in Other Domains with IGP Route Redistribution

Article | Feb. 20, 2017

One size does not always fit all. At times there’s a need to run more than one routing protocol and have more than one routing domain: multivendor shops, migration from one protocol to another, scalability issues of a single protocol, political or personal preference, production versus test networks, mergers, and acquisitions.

Know Your Options Before Selecting a Routing Protocol

Article | Feb. 07, 2017

Routers and switches make up the bulk of the network infrastructure and are vulnerable to attack. In a previous article, I talked about some of the different ways of hardening your network devices. In this blog, I’d like to specifically examine the routing protocols used on the major Cisco network operating systems.
