IP Routing

Introduction:

Routing refers to the process of transferring data from the source to the destination. It occurs at the network layer of the OSI model. A router selects the appropriate route for the data packets based on its routing tables. Every router maintains a routing table that stores different routes on the network. IP Routing provides a mechanism for the routers to connect networks and transfer data based on the IP header in the data packet.

Basic IP Traffic Management with Access lists

Introduction : 

The Access Control List (ACL) is a set of commands, which are grouped together. These commands enable to filter the traffic that enters or leaves an interface. A wildcard mask enables to match the range of address in the ACL statements. There are two references, which a router makes to ACLs, such as, numbered and named. These reference support two types of ;filtering, such as standard and extended. You need to first configure the ACL statements and then activate them.
