HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

391
To apply a new policy to outbound BGP sessions, execute this command with the export keyword. The
router uses the new policy to filter routing information and sends the routing information that passes the
filtering to the BGP peers.
To apply a new policy to inbound sessions, execute this command with the import keyword. The router
advertises a route-refresh message to the peer and the peer resends its routing information to the router.
After receiving the routing information, the router uses the new policy to filter the routing information.
This command requires that both the local router and the peer support route refresh.
If the peer keep-all-routes command is configured, the refresh bgp ipv4 unicast import command does
not take effect.
The command with the unicast keyword has the same effect as that without the unicast keyword.
Examples
# Manually soft-reset all BGP sessions for the IPv4 unicast address family.
<Sysname> refresh bgp ipv4 all
