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:
