CHAPTER 13 - Static Routing

Manually, dynamically

A router can learn about remote networks in what two ways?

Manually

way to learn about remote network. are manually entered into the route table using static routes.

Dynamically

way to learn about remote network. Remote routes are automatically learned using a dynamic routing protocol.

advertised

Static routes are not __________ over the network, resulting in better security.

Bandwidth

Static routes use less _________ than dynamic routing protocols, no CPU cycles are used to calculate and communicate routes.

Known

The path a static route uses to send data is _____

default static route

is a route that matches all packets. It identifies the gateway IP address to which the router sends all IP packets that it does not have a learned or static route.

default static route

is simply a static route with 0.0.0.0/0 as the destination IPv4 address

Next-hop route

next-hop option. Only the next-hop IP address is specified. (same with ipv6, just add ipv6)

Directly connected static route

next-hop option. Only the router exit interface is specified. (same with ipv6, just add ipv6)

Fully specified static route

next-hop option. The next-hop IP address and exit interface are specified. (same with ipv6, just add ipv6)

Floating static routes

have an administrative distance greater than the administrative distance of another static route or dynamic routes.

Floating static routes

The static route "floats" and is not used when the route with the better administrative distance is active.

Floating static routes

If the preferred route is lost, it can take over.

show ip route

Use the ____ __ _____ command to verify that the routing table is using the default/floating static route.

Traceroute

Use the traceroute command to follow the traffic flow out the primary/backup route.
