Default Policies and Actions

If an incoming or outgoing route or packet arrives and there is no explicitly configured policy related to the route or to the interface upon which the packet arrives, the action specified by the default policy is taken. A default policy is a rule or a set of rules that determine whether the route is placed in or advertised from the routing table, or whether the packet is accepted into or transmitted from the router interface.

All policies also have default actions in case one of the following situations arises during policy evaluation:

• A policy does not specify a match condition.
• A match occurs, but a policy does not specify an action.
• A match does not occur with a term in a policy and subsequent terms in the same policy exist.
• A match does not occur by the end of a policy.
