Distance Vector and Link State Routing Protocols

Sat, 01 Oct 2016 | Config Router

Now that you are aware of the routing methods available, this section looks at the two main types of routing methods that routers use to detect remote destinations dynamically. Distance vector protocols (a vector contains both distance and direction), such as RIP, determine the path to remote networks using hop count as the metric. A hop count is defined as the number of times a packet needs to pass through a router to reach a remote destination. For IP RIP, the maximum hop is 15. A hop count...

The Class B address 141.108.0.0 has been assigned to you for this task. You should ensure this address space is designed so that company growth allows you to use IP address space wisely to conserve it. Ensure summarization is possible with the three distribution routers. It is important that the IP addressing scheme is correctly laid out in a hierarchical fashion so that you can use summarization IP routing tables to keep them to a minimum. Start with the core of the network with a possible 20...

CCIE Lab Exam Test Format

Sat, 27 Jun 2015 | Config Router

Passing the qualification examination is the easier part of the CCIE exam journey. To pass the lab exam, your life needs to change dramatically, and you need to study on routers full time for at least three to six months. The good news is that the format of the lab examination has changed from two full days to one day only. You are no longer required to troubleshoot a network (regarded as the true method to test a CCIE's ability to restore a network back to full IP connectivity) you are now...
