Configuring DDR Backup Using Floating Static Route

To configure a floating static default route on the secondary interface, use the following commands, beginning in the global configuration mode.

Note Make sure you have ip classless enabled on your router.

SUMMARY STEPS

1.configure terminal

2.ip route network-numbernetwork-mask{ip address interface} [administrative distance] [name name]

DETAILED STEPS

	Command or Action	Purpose
Step 1	configure terminal	Enters global configuration mode from the terminal.
	Example:
	Router# configure terminal
Step 2	ip route network-number network-mask	Establishes a floating static route with the
	{ip-address interface} [administrative distance]	configured administrative distance through the
	[name name]	specified interface.
	Example:	A higher administrative distance should be
		configured for the route through the backup
	Router (config)# ip route 0.0.0.0 Dialer 2 track 234
		interface, so that the backup interface is used only
		when the primary interface is down.
