You don't need to restart the router. As Gustavo.HdezF said, if the services are not affected, you can use the reset bgp all command to reset all BGP connections. If you can confirm that these routes are not sent by BGP peers (you can disconnect the BGP peers connected to VLANIF 1010 to check whether these routes still exist.), there may be an unknown fault that occurs on the device. Please contact TAC to locate the fault.

Hello User. After you delete the configuration, did you execute the commit command? If you don´t do it, try it and tell us if the routes were deleted,

Hello User. You can try with the command reset bgp, in the following link you will find the description of the command:

Read carefully before to apply it to avoid any service interruption in your network.

Hi,

You can wait for a while for BGP to automatically refresh the routing table or use the refresh bgp command to actively refresh the bgp routing table. If these routes still exist after route refreshing, they may originate from other sources.
