What is the default value of the Local Preference attribute in BGP?

In Border Gateway Protocol (BGP), the Local Preference attribute is used to indicate the preferred exit point from the local Autonomous System (AS) for outbound traffic. When a BGP router receives multiple paths to a destination, it uses this attribute to determine which path to prefer.

The default value of the Local Preference attribute is 100. This means that if no other values have been explicitly set for Local Preference on routes, BGP considers the routes with this default value equally and will choose paths based on other criteria. When configuring BGP policies, administrators can adjust the Local Preference value to influence routing decisions, preferring higher values over lower ones.

Understanding the function and default settings of Local Preference is essential for BGP route selection and overall network traffic management.
