Parameters

Parameter	Description	Value
all	Softly resets all the BGP IPv4 connections.	-
ipv4-address	Specifies the IPv4 address of a BGP peer.	It is in dotted decimal notation.
external	Softly resets EBGP connections.	-
internal	Softly resets IBGP connections.	-
group group-name	Specifies the name of a BGP peer group.	The name is a string of 1 to 47 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
ipv6-address	Specifies the IPv6 address of a BGP4+ peer.	The address is in the format of X:X:X:X:X:X:X:X.
export	Triggers outbound soft resetting.	-
import	Triggers inbound soft resetting.	-
vpnv4	Softly resets the BGP connections in a VPNv4 address family.	-
vpn-instance vpn-instance-name	Softly resets the connection of a specified VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
ipv4-family	IPv4 address family.	-
vpnv6	Softly resets the BGP connections in a VPNv6 address family.	-
ipv6-family	IPv6 address family.	-
flow	Softly resets the BGP IPv4 connections in the BGP-Flow address family view.	-
labeled	Softly resets the BGP connections related to unicast labeled address family.	-
rpd	Softly resets the BGP connections related to RPD.	-

Usage Guidelines

Usage Scenario

If a device's peer supports route-refresh, the refresh bgp command can be used on the device to softly reset the BGP connection with the peer. BGP soft resetting can be used to refresh the BGP routing table and apply new routing policies, without closing any BGP connection.

Prerequisites

Configuring BGP soft resetting requires that the peers support the route-refresh capability.

Precautions

Assume that a device supports route-refresh and is configured with the peer keep-all-routes command. After the refresh bgp command is run on the device, the device does not refresh its routing table.

Example

# Perform a soft reset on all BGP connections in the inbound direction to make new configurations take effect.
