Operation Manual – TrackH3C S5500-EI Series Ethernet Switches Chapter 1 Track Configuration1-4I. Configuration prerequisitesBefore configuring VRRP to monitor a Track object, you need to create a VRRP groupon an interface and configure the virtual IP address of the VRRP group.II. Configuration procedureFollow these steps to configure Track-VRRP collaboration:To do… Use the command… RemarksEnter system view system-view —Enter interface view interface interface-typeinterface-number —Create a VRRP group andconfigure its virtual IPaddressvrrp vrid virtual-router-idvirtual-ip virtual-addressRequiredNo VRRP group iscreated by default.Specify a Track object tobe monitored by VRRPvrrp vrid virtual-router-idtrack track-entry-number[ reducedpriority-reduced |switchover ]RequiredNo Track object isspecified for VRRP bydefault.Note:z Do not perform Track object monitoring on the IP address owner.z When the status of the monitored Track object turns from Negative to Positive, thecorresponding master restores its priority automatically.z The monitored Track object can be nonexistent, so that you can first specify theTrack object to be monitored using the vrrp vrid track command, and then createthe Track object using the track command.z Refer to VRRP Configuration for details of VRRP.1.4.2 Configuring Track-Static Routing CollaborationYou can check the validity of a static route in real time by establishing collaborationbetween Track and static routing.If you specify the next hop but not the egress interface when configuring a static route,you can associate the static route with a Track object and thus check the validity of thestatic route according to the status of the Track object.z If the status of the Track object is Positive, then the next hop of the static route isreachable, and the configured static route is valid.z If the status of the Track object is Negative, then the next hop of the static route isunreachable, and the configured static route is invalid.
