Action
Policy Actions can contain the following attributes:
-
Packet Action —Choose to accept the route and propagate it (or reject it) here. After accepting a
route, no other terms in the routing policy and no other routing policies are evaluated. After
you reject a route, no other terms in the routing policy and no other routing policies are
evaluated.
-
Next —Select next Policy to skip to and evaluate the next routing policy. Any accept or reject
action specified in the
then statement is skipped. Any actions in the then statement that
manipulate route characteristics then apply to the route. Next
Policy is the default control
action if a match occurs, if you do not specify a flow control action, and there are no further
terms in the current routing policy. You can select the next
Te rm to skip to and evaluate the
next term in the same routing policy. Any accept or reject action specified in the
then
statement is skipped. Any actions in the
then statement that manipulate route characteristics
are applied to the route.
-
Local Preference —(BGP only) Set the BGP local preference (LOCAL_PREF) attribute. The
preference value can be a number in the range from 0 through 4,294,967,295 (232 -1).
When you use
add/subtract instead of default, you can change the local preference value by
the specified amount. If an addition operation results in a value that is greater than
4,294,967,295 (232 - 1), the application sets the value to 232 - 1. If a subtraction operation
results in a value less than zero (0), the application sets the value to zero. If an attribute value
is not already set at the time of the addition or subtraction operation, the attribute value
defaults to a value of zero (0) regardless of the amount specified. If you perform an addition
to an attribute with a value of zero, the number you add becomes the resulting attribute
value.
