Static routes
Objectives Describe what a static route is Define what administrative distance refers to Describe how to configure a static route
Static routes Static routes are commonly used when routing
from a network to a stub network A stub network is a network that can only be
accessed by one route Routing protocols used in stub networks can
be a waste of resources Therefore static routes are configured for
connectivity to remote networks that are not directly connected to a router
Static route operation Next hop address
Next hop IPaddress
Administrative distance A measure of reliability When there are two or more protocols
showing two or more routes to a destination, the router uses the admin distance to determine which protocol to use
Lower values are more reliable Static routes have a default admin distance of
1 However, a true directly connected route has
an admin distance of 0! To verify the administrative distance use
show ip route address
Configuring static routes
Hoboken must be configured so that it can reach the 172.16.1.0 network and the 172.16.5.0 network. Both of these networks have a subnet mask of 255.255.255.0.
Hoboken(config)#ip route 172.16.1.0 255.255.255.0 s1Hoboken(config)#ip route 172.16.5.0 255.255.255.0 s0

Default routes are used to route packets with destinations that do not match any of the other routes in the routing table

Summary Static and dynamic routing is often used
together Static routes are commonly used with stub
networks i.e. networks with only one way to access them
Administrative distance is a measure of reliability
