peer keychain (BGP-VPN instance view) (group)

Format

peer group-name keychain keychain-name

undo peer group-name keychain

Parameters

Parameter	Description	Value
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.
keychain-name	Specifies the name of the Keychain authentication. Before configuring this parameter, run the keychain command to create a keychain. Then, run the key-id, key-string, and algorithm commands to configure a key ID, a password, and an authentication algorithm for this keychain. Otherwise, the authentication will fail, and the BGP peer relationship fails to be established. If the dependent keychain is deleted, the neighbor relationship may be interrupted. Therefore, exercise caution when deleting the keychain.	The value is a string of 1 to 47 case-sensitive characters without any space. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

Configuring Keychain authentication improves the security of the TCP connection. You must configure Keychain authentication specified for TCP-based applications on both BGP peers. Note that encryption algorithms and passwords configured for the Keychain authentication on both peers must be the same; otherwise, the TCP connection cannot be set up between BGP peers and BGP messages cannot be transmitted.

Prerequisites

Before configuring the BGP Keychain authentication, a Keychain in accordance with the configured keychain-name must be configured first.

Precautions

The peer keychain command and the peer password command are mutually exclusive.

Example

# Configure the Keychain authentication named Huawei for BGP peer group.
