IP Routing
IP routing is the forwarding of IP packets by routers throughout a network. Routers look at the destination IP address in an IP packet and decide where it has to be forwarded to. Routers use routing protocols like OSPF, EIGRP and BGP to learn network routes.
Here you will find a variety of lessons that are related to IP routing. For example, some lessons explain how to configure redistribution between two routing protocols. We also cover things like route filtering or policy based routing here. There are also examples how you can use GRE tunneling, how to configure different interfaces like a 3G/4G cellular interface and more.
