export: Soft resets outbound EBGP sessions.

import: Soft resets inbound EBGP sessions.

Usage guidelines

Soft reset can update BGP VPNv4 routing information without breaking down BGP neighbor

relationships.

You can apply a new route selection policy by executing this command. If you execute this command with

the export keyword, BGP filters advertised routing information based on the new policy and sends the

matching routes to the BGP peer. If you execute this command with the import keyword, BGP advertises

a route-refresh message to the peer so the peer re-advertises its routing information. After receiving the

routing information from the peer, BGP filters the routing information by using the new policy.

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 vpnv4 import command does not

take effect.

Examples

# Manually soft reset all inbound BGP sessions for VPNv4 address family.

<Sysname> refresh bgp all import vpnv4
