Backup; Configuring Policy-Based Routing - Avaya G250 Administration

Backup

You can utilize policy-based routing to define backup routes for defined classes of traffic. If the
first route on the next hop list fails, the packets are routed to a subsequent hop. When
necessary, you can use the NULL interface to drop packets when the primary next hop fails. For
example, voice packets are usually sent over a WAN line, and not the Internet. You can
configure a PBR list to drop voice packets when the WAN line is down.

Configuring policy-based routing

For a full example of a policy-based routing configuration, see
page 562.
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)#
