Parameter
all: Refreshes all peers.
ip-address: Refreshes connection with a specified BGP peer.
group-name: Peer group name, containing 1 to 47 characters.
multicast: Specifies multicast address family.
import: Sends a ROUTE-REFRESH packet to the peer, requesting the peer to
refresh the routes.
export: Refreshes routes advertised to the peers.
Description
Use the refresh bgp command to manually refresh BGP connections. Refreshing
BGP connections can refresh the BGP routing table without interruption any BGP
connection and apply a new policy.
After a BGP connection is created, only incremental routes are sent. However, in
some cases, such as when BGP routing policy changes, the peer needs to
re-advertise .routes or to be resent routes so that the routes are filtered again
according to the new policy.
Example
# Refresh all BGP connections.
<3Com> refresh bgp all import
