How not to route on a Cisco router

As an IT administrator, it is important to understand how to configure a Cisco router properly to avoid routing issues. In this article, we will discuss the best practices for avoiding routing issues on a Cisco router.

First, it is important to make sure that you are using a valid IP addressing scheme. It is important to use a scheme that follows the standards of IP routing. This means that you should use a scheme that follows the classful addressing rules of IP routing. If you are using a classless addressing scheme, you should make sure that you are using the proper subnets and masks.

Second, it is important that you configure the router with the proper routing protocols. You need to make sure that you are using the appropriate routing protocols for your network environment. For example, if you are using an IPv4 network, then you should be using either RIP or OSPF. If you are using an IPv6 network, then you should be using RIPng or OSPFv3.

Third, you should configure the router to use the appropriate type of route summarization. Route summarization is used to reduce the amount of routes that need to be maintained in the routing table. It is important that you use the correct type of summarization for your network environment.

Fourth, you should configure the router to use the proper route filtering and route redistribution. Route filters are used to control the routes that are admitted and redistributed into the routing table. It is important to make sure that you are using the appropriate route filtering and route redistribution to ensure that the routes that are being admitted into the routing table are valid.

Fifth, you should configure the router to use the proper route maps. Route maps are used to control the routes that are being advertised out of the router. It is important to make sure that you are using the proper route maps for your network environment.

Finally, you should configure the router to use the proper route metrics. Route metrics are used to determine which routes are the best to use. It is important to make sure that you are using the proper route metrics to ensure that the router is selecting the best routes.

In conclusion, it is important to understand how to configure a Cisco router properly to avoid routing issues. By following the best practices outlined in this article, you should be able to avoid routing issues on your Cisco router.
