Next hop list 1 sends packets that match the rule in which it is included to theE1/T1 line (serial interface 4/1). If that interface is not available, the next hop list requires thepacket to be dropped (Null0). This is because the QoS on the Internet interface is not adequatefor voice packets. It would also be possible to include one or more backup interfaces in the nexthop list.G350-001(super)# ip next-hop-list 1G350-001(super-next hop list 1)#name "Voice-To_HQ"Done!G350-001(super-next hop list 1)#next-hop-interface 1 Serial 4/1Done!G350-001(super-next hop list 1)#next-hop-interface 2 Null0Done!G350-001(super-next hop list 1)#exitG350-001(super)#The next set of commands applies the PBR list to the voice VLAN (6).G350-001(super)# interface Vlan 6G350-001(super-if:Vlan 6)# ip pbr-group 801Done!G350-001(super-if:Vlan 6)# exitG350-001(super)#The next set of commands applies the PBR list to the Loopback interface. This is necessary toensure that voice packets generated by the G350 itself are routed via the E1/T1 line. TheLoopback interface is a logical interface that is always up. Packets sent from the G350, such assignaling packets, are sent via the Loopback interface. In this example, applying PBR list 801 tothe Loopback interface ensures that signaling packets originating from voice traffic are sent viathe T1/E1 line.G350-001(super)# interface Loopback 1G350-001(super-if:Loopback 1)# ip pbr-group 801Done!G350-001(super-if:Loopback 1)# exitG350-001(super)#Issue 3 January 2005 285
