Timebased BGP

how to configure BGP advertisements through prefix-list in time-based manner,

[paolo bevilacqua]

Since I don't think that prefix-list allows time-range, either you work out a configuration that can work with time-based regular ACL, or use TCL EEM:

This way you can do any configuration change based on events or schedules.

Hope this helps, please rate post if it does!
