180 seconds
Cisco Discovery Protocol is a proprietary protocol to allow
you to access configuration information on other routers
and switches with a single command. It uses SNAP at the
Data-Link Layer. By default CDP sends out a broadcast every
60 seconds and it holds this information for 180 seconds.
CDP is enabled by default.

Global CDP information:
Sending CDP packets every 60 seconds
Sending a holdtime value of 180 seconds
But you can also set CDP timer and holdtime values.

Enter configuration commands, one per line. End with
CNTL/Z.
Router_2(config)#cdp timer 90
Router_2(config)#cdp holdtime 360

I was doing some ODR routing labs today and started mucking about with CDP timers (ODR uses CDP for advertisements). This is important to note in case you get a task that requires you to change the convergence time of an ODR learned route. CDP timers are changed at the global level. The default values are 60 seconds for advertisements with a 180 second holddown time.
