The refresh bgp command softly resets a BGP connection. BGP soft reset can be used to refresh the BGP routing table and apply new routing policies, without closing any BGP connection.

| 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 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.
