You can define a particular path as more preferable or less preferable than other paths by changing the
default local preference value of 100. To assign a different default local preference value, use the

You can use route maps to change the default local preference of specific paths. See the “BGP Route
Map Examples” section at the end of this chapter for examples when used with BGP route maps.
