Configuring additional VRRP and VRRPE parameters 31 Syntax: backup [priority ] [track-priority ] The priority parameter specifies the VRRP priority for this interface and VRID. You can specify a value from 3 - 254. The default is 100. The track-priority parameter is the same as above. NOTE You cannot set the priority of a VRRP Owner. The Owner priority is always 255. VRRPE syntax Syntax: backup [priority ] [track-priority ] The software requires you to identify a VRRPE interface as a Backup for its VRID before you can activate the interface for the VRID. However, after you configure the VRID, you can use this command to change its priority or track priority. The parameter values are the same as for VRRP. Suppression of RIP advertisements on Backup routers for the Backup interface Normally, a VRRP or VRRPE Backup includes route information for the virtual IP address (the backed up interface) in RIP advertisements. As a result, other routers receive multiple paths for the backed up interface and might sometimes unsuccessfully use the path to the Backup rather than the path to the Master. You can prevent the Backups from advertising route information for the backed up interface by enabling suppression of the advertisements. To suppress RIP advertisements for the backed up interface in Router2, enter the following commands. Router2(config)#router rip Router2(config-rip-router)#use-vrrp-path Syntax: use-vrrp-path The syntax is the same for VRRP and VRRPE. Hello interval The Master periodically sends Hello messages to the Backups. The Backups use the Hello messages as verification that the Master is still on-line. If the Backup routers stop receiving the Hello messages for the period of time specified by the Dead interval, the Backup routers determine that the Master router is dead. At this point, the Backup router with the highest priority becomes the new Master router. The Hello interval can be from 1 - 84 seconds. The default is 1 second. NOTE The default Dead interval is three times the Hello Interval plus one-half second. Generally, if you change the Hello interval, you also should change the Dead interval on the Backup routers. To change the Hello interval on the Master to 10 seconds, enter the following commands. Router1(config)#inter e 1/6 Router1(config-if-1/6)#ip vrrp vrid 1 Router1(config-if-1/6-vrid-1)#hello-interval 10 Syntax: hello-interval The syntax is the same for VRRP and VRRPE.
