#7thingsWeLearntStaticRouting
Static routing is a type of network routing where network administrators manually configure the routing tables of routers and switches. In static routing, the routes to specific destinations are explicitly defined and do not change unless the administrator manually updates the routing table.
- Static Routing has an administrative distance of 1 and it can be redistributed by all dynamic routing.
- It is usually manually configured in the router, and it is configured like this: Ip route (network-address) (subnet-mask) (next-hop ip address/ exit interface) [cisco routing syntax]
- Despite its simplicity, static routing has limitations, especially in large and dynamic networks, it is not scalable.
- Unlike Dynamic routing protocols such as EIGRP, OSPF or BGP static routing does not have room to exchange routing updates with the next router.
- There is very minute CPU intensity required to run static routing in a router Static routing instance.
- Static routing is generally prone to errors since it is manually configured.
- The only attempt to make static route dynamic is by configuring it with an ip sla track. We locally referred to this process as “floating static routing.”
It generally acts as an alternative to dynamic routing to provide failsafe backup if the dynamic routes are not accessible.
Static Routing is also known as non-adaptive routing which doesn’t change the routing table unless the network administrator changes or modifies them manually. Static routing does not use complex routing algorithms and It provides high or more security than dynamic routing
