Parameter
all: Refreshes all the peers.
peer-address: Refreshes the peer with the specified address.
group-name: Refreshes all the members in the specified peer group.
vpnv4: Refreshes routes of VPNv4 address family for the peer.
multicast: Refreshes routes of multicast address family for the peer.
vpn-instance vpn-instance-name: Refreshes VPN routes for the peer in the specified
VPN-INSTANCE.
import: Sends ROUTE-REFRESH packet to the peer to require retransmission of all
the routes.
export: Retransmits all the routes to the peer.
Description
Use the refresh bgp command to request the peer to retransmit routes or retransmit
routes to the peer.
After a BGP connection is created, only incremental routes are transmitted. But in some
cases, for example, when the routing policy is changed, retransmission of routes is
required on both ends, and the routes will be filtered according to the new policy.
Example
# Request all the peers to retransmit multicast routes.
<3Com > refresh bgp all multicast import
# Retransmit all the routes to the CE peer 10.1.1.1 in VPN-INSTANCE vpn1.
<3Com > refresh bgp 10.1.1.1 vpn-instance vpn1 export
