Your choices as a network administrator are to use dynamic routing protocols on your network or stick to static routing, which is where you manually add each route for your network onto each router.
I’m often asked which routing protocol is the “best.” There is no method which will suit every network, as even a particular company’s network requirements will change over time. Static routing will take time and effort to configure, but you will save on network bandwidth and CPU cycles. If a new route is added, then you will have to add this manually to every router. In addition, if a route goes down, static routing has no method to deal with this, so it will continue to send traffic to the down network (reliable static routing is outside the CCNA syllabus).
Today you will learn about the following:
- Configuring static routes
- Troubleshooting static routes
This module maps to the following CCNA syllabus requirements:
ü Configure and verify the routing configuration for a static or default route given specific routing requirements
ü Differentiate methods of routing and routing protocols
- Static vs. dynamic
- Next hop
If you look back at the administrative distances table in Day 10, you will see that manually configured networks are preferred over routing protocols. The reason for this is, as a network administrator, you will be expected to know your network better than any protocol can and to understand what you want to achieve. By now, it should be clear that you can use static routing with dynamic routing if your needs require it.
