| Parameter | Description | Value |
|---|---|---|
vpn-instance vpn-instance-name ipv4-family |
Resets the connection of a specified VPN instance enabled with an IPv4 address family. |
The value must be an existing VPN instance name. |
vpnv4 |
Resets BGP connections associated with VPNv4. |
- |
all |
Resets all BGP connections. |
- |
as-number-plain |
Specifies the number of the AS, in integer format. |
The value is an integer that ranges from 1 to 4294967295. |
as-number-dot |
Specifies the number of the AS, in dotted notation. |
The value is in the format of x.y, where x and y are integers that range from 1 to 65535 and from 0 to 65535, respectively. |
ipv4-address |
Resets the BGP connection with a specified peer. |
It is in dotted decimal notation. |
group group-name |
Resets the BGP connection with a specified 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. |
external |
Resets all EBGP connections. |
- |
internal |
Resets all IBGP connections. |
- |
ipv4 |
Resets BGP IPv4 connections. |
- |
ipv6 |
Resets BGP IPv6 connections. |
- |
ipv6-address |
Resets the TCP connection with a specified BGP4+ peer (all the routes learned by using the connection are deleted). |
The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X. |
vpls |
Resets BGP connections associated with VPLS. |
- |
vpnv6 |
Resets BGP connections associated with VPNv6. |
- |
vpn-instance vpn-instance-name ipv6-family |
Resets the connection of a specified VPN instance enabled with an IPv6 address family. |
The value must be an existing VPN instance name. |
graceful |
Resets BGP connections in GR mode. |
- |
Usage Scenario
The reset bgp command is used to make new BGP configurations take effect.
If a BGP routing policy is configured on the device that does not support Route-Refresh, the reset bgp command can be used to make the new routing policy to take effect.
To reset a BGP connection in GR mode, run the reset bgp command with the graceful parameter specified and run the graceful-restart peer-reset command. If the graceful parameter is not specified in the reset bgp command or if the graceful-restart peer-reset command is not run, the GR reset mode does not take effect, so that routing entries will be deleted for existing sessions, interrupting services. The services will be restored after the BGP peer relationship is reestablished.
The reset bgp ipv4 all command resets all public-network BGP IPv4 connections.
Precautions
After the reset bgp command is run on a device, the TCP connection established by the BGP device and the corresponding peer is reestablished. Exercise caution when running this command.
