The route map with a deny statement uses the following logic:

The incoming packet is matched against the criteria in the match term specified in the

route map. This match command can refer to an IP/MAC access list. An ACL that is used

in the match term itself has one or more permit or deny rules. Now, the incoming packet is

matched against the rules in the ACL, and a permit or deny decision is reached.

If the decision reached in the previous step is permit, then policy-based routing

processing logic terminates and the packet goes through standard destination-based

routing logic.

If the decision reached in the earlier step is deny, the counter for this match statement is

not incremented and the processing logic moves to next route-map statement in the

sequence. If no next route-map statement exists, the processing logic terminates and the

packet goes through standard destination-based routing logic.

The following table specifies the desired actions:

Table 1. Desired actions

The following actions are taken:

Next. Fall through to the next route map, and if no further route maps exist, route using

the default routing table.

Set. Route according to the action in the set clause.

Route (alone). Route using the default routing table.

PBR Configurations

PBR is configurable on the following types of eligible routing interfaces:

Physical ports

VLAN interfaces

On VLAN interfaces, when an ACL is applied, it implies that when any packet arrives with a

corresponding VLAN ID on any port, it is matched and a corresponding action is taken.
