Parameters

ipv6-address: Soft-resets the BGP session to the specified peer. The ipv6-address argument refers to the IPv6 address of a peer.

all: Soft-resets all BGP sessions.

external: Soft-resets all EBGP sessions.

group group-name: Soft-resets the BGP sessions to the peers of the specified peer group. The group-name argument refers to the name of a peer group, a case-sensitive string of 1 to 47 characters.

internal: Soft-resets all IBGP sessions.

export: Performs outbound soft-reset (filters routes advertised to the specified peer or peer group by using the new configuration).

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
