Chapter 2 Advanced Routing for FortiOS 5.0 : Border Gateway Protocol (BGP) : Troubleshooting BGP : Clearing routing table entries
  
Clearing routing table entries
To see if a new route is being properly added to the routing table, you can clear all or some BGP neighbor connections (sessions) using the execute router clear bgp command.
For example, if you have 10 routes in the BGP routing table and you want to clear the specific route to IP address 10.10.10.1, enter the command:
execute router clear bgp ip 10.10.10.1
To remove all routes for AS number 650001, enter the command:
execute router clear bgp as 650001
