You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation
updates BGP routing information without tearing down BGP connections. A reset operation updates
BGP routing information by tearing down, and then re-establishing BGP connections. Soft reset
requires that BGP peers have route refresh capability.
Execute the following commands in user view to soft reset or reset BGP connections:
