Configuring Floating Static Routes

Static and dynamic routes are the two components of floating static routes. Perform these steps to configure the static and dynamic routes on your router, beginning in global configuration mode:

 

Command

 

 

Purpose

Step 1

 

 

ip route prefix mask {ip-address interface-type

Assigns the primary static route.

 

interface-number [ip-address]}

 

 

Example:

 

 

 

 

Router(config)#

ip route 0.0.0.0 0.0.0.0

 

 

22.0.0.2

 

 

 

 

Router(config)#

 

 

Step 2

 

 

ip route prefix mask {ip-address interface-type

Assigns the lower routing administrative distance

 

interface-number [ip-address]} [distance]

value for the backup interface route. 192.168.2.2

 

 

 

 

is the peer IP address of the backup interface.

 

Example:

 

 

 

 

Router(config)#

ip route 0.0.0.0 0.0.0.0

 

 

192.168.2.2

150

 

 

 

Router(config)#

 

 

Step 3

 

 

 

 

router rip

 

 

Enables RIP routing.

 

Example:

 

 

 

 

Router(config)#

router rip

 

 

Router(config)#

 

 

Step 4

 

 

network ip-address

Defines the primary interface network. 22.0.0.0 is

 

 

 

 

the network value of the primary interface.

 

Example:

 

 

 

 

Router(config)#

network 22.0.0.0

 

 

Router(config)#

 

 

Step 5

 

 

ip route prefix mask {ip-address interface-type

Assigns the lower routing administrative distance

 

interface-number [ip-address]} [distance]

value for the backup interface route. 192.168.2.2

 

 

 

 

is the peer IP address of the backup interface.

 

Example:

 

 

 

 

Router(config)#

ip route 0.0.0.0 0.0.0.0

 

 

192.168.2.2

150

 

 

 

Router(config)#

 

 

 

 

 

 

 

Note When dynamic routing is activated, the floating static route depends upon routing protocol convergence times.
