Chapter 40 Configuring Policy-Based Routing
Policy-Based Routing Configuration Tasks
Note PBR configuration is only allowed on interfaces belonging to the global routing table. PBR is not
supported on interfaces that belong to VRFs.
Policy-Based Routing Configuration Tasks
To configure PBR, perform the tasks described in the following sections. The task in the first section is
required; the tasks in the remaining sections are optional. For configuration examples, see the
“Policy-Based Routing Configuration Examples” section on page 40-12.
• Enabling IPv4 PBR, page 40-6 (Required)
• Enabling IPv6 PBR, page 40-8 (Required)
• Enabling Local IPv4 and Local IPv6 PBR, page 40-11 (Optional)
• Examples of the show Command, page 40-11 (Optional)
• Unsupported Commands, page 40-11
Enabling IPv4 PBR
To enable PBR, you must create a route map that specifies the match criteria and the resulting action if
all of the match clauses are met. Then you must apply that route-map on a particular interface. All
packets arriving on the specified interface matching the match clauses are subject to PBR.
To enable IPv4 PBR on an interface, perform this task:
Command Purpose
Step 1
Switch(config)# route-map map-tag [permit |
deny] [sequence-number]
Defines a route map to control where packets are sent. This
command puts the switch into route-map configuration mode.
Step 2
Switch(config-route-map)# match ip address
{access-list-number | name}
[...access-list-number | name]
Specifies the match criteria. The match criteria take the form
of one or more Standard or Extended IP access-lists. The
access-lists can specify the source and destination IP
addresses, protocol types, and port numbers.
Step 3
Switch(config-route-map)# set ip next-hop
ip-address [... ip-address]
Or
Specifies the next-hop IP address to which matching packets
are sent. The next-hop IP address specified here must belong
to a subnet that is directly connected to this switch.
If more than one next-hop IP address is specified, the first
usable next-hop is chosen for routing matching packets. If the
next-hop is (or becomes) unavailable for some reason, the
next one in the list is chosen.
