4000 Router Series Layer 3 - IP Routing Command Reference

392

import: Performs inbound soft-reset (filters routes received from the specified peer or peer group by using

the new configuration).

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string

of 1 to 31 characters. If no VPN instance is specified, this command performs manual soft-reset on BGP

sessions for the public network IPv6 unicast address family.

Usage guidelines

After the route selection policy is modified, execute this command with the export keyword to enable the

local router to filter routing information based on the new policy and send the matching routes to the BGP

peer. If you execute this command with the import keyword, you enable the local router to advertise a

route-refresh message to the peer and the peer resends its routing information to the router. After

receiving the routing information, the router 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 ipv6 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 IPv6 unicast address family.

<Sysname> refresh bgp all ipv6

Usage guidelines

To apply a new route selection policy, use this command to reset BGP sessions. BGP re-establishes the

BGP sessions, advertises routes, and applies the new policy to routes. This operation breaks down BGP

sessions for a short while.

Examples

# Reset all BGP sessions.

<Sysname> reset bgp all
