Configuring policy-based routing

Configuring policy-based routing
For a full example of a policy-based routing configuration, see Application example on
page 674.
1. Define PBR lists.
●
In general context, enter
ip pbr-list
followed by a list number in the range
800-899. For example:
●
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:
●
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:
2. Define PBR rules.
In the PBR list context, enter
ip-rule
, 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
Application example on
page 674.
Note:
Note:
It is recommended to leave a gap between rule numbers, in order to leave room
for inserting additional rules at a later time. For example, ip-rule 10, ip-rule 20,
ip-rule 30.
