Resetting BGP connections
When BGP configuration changes, you can use the soft reset function or reset BGP connections to
make new configurations take effect. Soft reset requires that BGP peers have route refreshment
capability (supporting Route-Refresh messages).
NOTE:
Soft reset of BGP connections refers to updating BGP routing information without breaking BGP
neighbor relationships. Hard reset of BGP connections refers to updating BGP routing information
by breaking and then reestablishing BGP neighbor relationships.
Use the following commands to hard reset or soft reset BGP connections:
