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.

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.
