542 CHAPTER 27: BGP CONFIGURATION COMMANDS
After the BGP connection is established, only incremental routes are sent.
However, some special cases exist. For example, when the routing policy changes,
the routes advertised to the peer or the advertised routes from the peer need
refreshing so that they can be filtered according to the new policy.
Example
# Request all peers to re-send the routes.
<SW8800>refresh bgp all import
reset bgp Syntax
reset bgp { all | peer-address [ flap-info ] }

Parameter
peer-address: Resets the connection with a specified BGP peer.
all: Resets all the connections with BGP.
flap-info: Resets the flap-info of a record at this peer address.
Description
Use the reset bgp peer-address command to reset the connection of BGP with a
specified BGP peer.
Use the reset bgp all command to reset all the connections with BGP.
If the BGP policy or the protocol configuration changes, resetting the BGP
connection can make the newly configured policy take effect immediately.
Example
# Reset all the BGP connections to enable the new configuration (after configuring
the new Keepalive interval and Holdtime interval using the timer command).
<SW8800> reset bgp all

path regular expression.
