Configuring policy-based routingConfiguring Policy-Based RoutingThis section provides step-by-step instructions for configuring policy-based routing on aninterface. For a full example of a policy-based routing configuration, see Application example onpage 283.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. Forexample:G350-001(super)# ip pbr-list 802G350-001(super-PBR 802)#To assign a name to the list, use the name command, followed by a text string, in the PBRlist context. The default name is list #. 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 thePBR 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, todefine a rule for the PBR list. Repeat this command to define additional rules. A rulecontains (i) criteria that is matched against the packet, and (ii) a next hop list. When apacket matches the criteria specified in the rule, the rule’s next hop list determines how thepacket is routed. Each PBR list can have up to 1,500 rules. The first rule that matches thepacket determines the packet’s routing.It is important to include a destination address, or range of addresses, in PBR rules to betterclassify the traffic to be routed. For an illustration, see Application example on page 283.Note:Note:It is recommended to leave a gap between rule numbers, in order to leave roomfor inserting additional rules at a later time. For example, ip-rule 10, ip-rule 20,ip-rule 30.276 Administration of the Avaya G350 Media Gateway
