BGP Peer

Nodes that establish connections within different AS or the same AS to exchange routing information. These nodes communicate through the BGP protocol.

Terminology

Term	Explanation
AS Number	An AS (Autonomous System) is a collection of routers under the same technical administration, using a unified routing policy. Each AS in the BGP network is assigned a unique AS number to distinguish different ASes. AS numbers are categorized into 2-byte and 4-byte AS numbers. The range for 2-byte AS numbers is 1~65535, where 1-64511 are publicly registered AS numbers on the Internet, similar to public IP addresses; 64512~65535 are private AS numbers, similar to private IP addresses. The range for 4-byte AS numbers is 1~4294967295. Devices that support 4-byte AS numbers can be compatible with devices that support 2-byte AS numbers.

AS Number

An AS (Autonomous System) is a collection of routers under the same technical administration, using a unified routing policy. Each AS in the BGP network is assigned a unique AS number to distinguish different ASes. AS numbers are categorized into 2-byte and 4-byte AS numbers.

The range for 2-byte AS numbers is 1~65535, where 1-64511 are publicly registered AS numbers on the Internet, similar to public IP addresses; 64512~65535 are private AS numbers, similar to private IP addresses.
The range for 4-byte AS numbers is 1~4294967295.

Devices that support 4-byte AS numbers can be compatible with devices that support 2-byte AS numbers.

Notes

BGP mode does not support the IPv6 protocol.

Prerequisites

Please contact the administrator to enable the related features.

Steps

In the left navigation bar, click Networking > BGP Peer.
Click Create BGP Peer.

Configure the parameters according to the following descriptions.

Parameter	Description
Local AS	The AS number of the AS where the BGP connection node is located. Note: If there are no special requirements, it is recommended to use IBGP configuration, meaning the local AS number is the same as the peer AS number.
Remote AS	The AS number of the AS where the BGP peer is located.
Remote IP	The IP address of the BGP peer, which needs to be a valid IP address capable of establishing a BGP connection.
Local IP	The IP address of the BGP connection node. When the BGP connection node has multiple IPs, select the specific local IP to establish the BGP connection with the peer.
Remote Port	The port number of the BGP peer.
BGP connection node	The node that establishes the BGP connection. If this parameter is not configured, all nodes will establish BGP connections.
