Configuring policy-based routing

Configuring policy-based routing
This section provides step-by-step instructions for configuring policy-based routing on an
interface. For a full example of a policy-based routing configuration, see
page 475.
To configure policy-based routing:
1. Define PBR lists.
In general context, type ip pbr-list, followed by a list number in the range 800-899. For
example:
G350-001(super)# ip pbr-list 802
G350-001(super-PBR 802)#
To assign a name to the list, use the name command, followed by a text string, in the PBR
list context. The default name is list #<list number>. For example:
G350-001(super-PBR 802)# name "voice"
Done!
G350-001(super-PBR 802)#
To assign an owner to the list, use the owner command, followed by a text string, in the
PBR list context. The default owner is other. For example:
G350-001(super-PBR 802)# owner "tom"
Done!
G350-001(super-PBR 802)#
2. Define PBR rules.
In the PBR list context, use the ip-rule command, followed by the number of the rule, to
define a rule for the PBR list. Repeat this command to define additional rules. A rule
contains (i) criteria that is matched against the packet, and (ii) a next hop list. When a
packet matches the criteria specified in the rule, the rule's next hop list determines how the
packet is routed. Each PBR list can have up to 1,500 rules. The first rule that matches the
packet determines the packet's routing.
It is important to include a destination address, or range of addresses, in PBR rules to better
classify the traffic to be routed. For an illustration, see
Note:
It is recommended to leave a gap between rule numbers, in order to leave room
Note:
for inserting additional rules at a later time. For example, ip-rule 10, ip-rule 20,
ip-rule 30.
