Description
Using the refresh bgp command, you can request the peer for route
retransmission or retransmit routes to the peer.
After BGP connection is created, only incremental routes are transmitted. But in
some cases, for example, when routing policy is changed, retransmission of routes
is required on both ends. And the routes should be filtered again 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
