Overview of the Local Preference BGP Attribute
The Local Preference BGP Attribute is an important part of the Border Gateway Protocol (BGP). It is used to identify the best path for forwarding traffic from one Autonomous System (AS) to another. The Local Preference BGP Attribute allows an administrator to control how the BGP route selection process occurs and is applied to routes that are learned from a local BGP speaker. The attribute is used in order to determine which routes should be chosen over others when multiple paths exist to the same destination. By using the Local Preference BGP Attribute, an administrator can prioritize certain routes or select specific routes to be used.
How to Use the Local Preference BGP Attribute
The Local Preference BGP Attribute is used to influence a router’s decision on which paths to use when deciding where to send packets. It is assigned to each route within the network, and it is the highest attribute that can be used to influence the path selection. When multiple routes are available for a destination, the router will select the route with the highest local preference value. The higher the value, the more likely it is for the router to choose it. The default local preference value is 100, but this can be adjusted according to individual needs.
When to Use the Local Preference BGP Attribute
The Local Preference BGP Attribute is most commonly used when a network is configured with multiple BGP routes, each with different attributes. This attribute can be used to determine which route is preferred, allowing the network administrator to adjust traffic flow as needed. In addition, the Local Preference BGP Attribute can be useful when configuring specific routes that should be used before others. This is especially useful for services that require a high level of reliability and redundancy.
