1. Static Routing.
Static routing occurs when you manually add routes in each router’s routing table.
By default, Static routes have an Administrative Distance (AD) of 1
Features
- There is no overhead on the router CPU
- There is no bandwidth usage between routers
- It adds security, because the administrator can choose to allow routing access to certain networks only.
2. Default Routing.
Default routing is used to send packets with a remote destination network not
in the routing table to the next-hop router
3. Dynamic Routing.
Dynamic routing is when protocols are used to find networks and update routing table on routers.
A routing protocol defines the set of rules used by router when it communicates routing information between neighbor routers
