Required
By default, no route-policy is
defined.
Note:
z
The
permit
argument specifies the matching mode for a defined node in the
route-policy to be in
permit
mode. If a route matches the rules for
the node, the
apply
statements for the node will be executed and the test of the next node will not
be taken. If not, however, the route takes the test of the next node.
z
The
deny
argument
specifies the matching mode for a defined node in the
route-policy to be in
deny
mode. In this mode, no
apply
clause is executed. If a
route satisfies all the
if-match
statements of the node, no
apply
clause for the node
will be executed and the test of the next node will not be taken. If not, however, the
route takes the test of the next node.
z
If multiple nodes are defined in a route-policy, at least one of them should be in
permit
mode. When a route-policy is applied to filtering routing information, if a
piece of routing information does not match any node, the routing information will be
denied by the route-policy. If all the nodes in the route-policy are in
deny
mode, all
routing information will be denied by the route-policy.
