Figure 6-236 VRRP Settings (Edit) Window The fields that can be configured are described below: Parameter Advertisement Interval Preemption Priority BFD Remote IP Critical IP Address Shutdown Description Enter the advertisement interval value here. This is the time interval between successive VRRP advertisements by the master router. The range is from 1 to 255 seconds. By default, this value is 1 second. Select to enable or disable the preemption feature here. This feature is used to allow a router to take over the master role if it has a better priority than the current master. Enter the priority value here. The range is from 1 to 254. Enter the Bidirectional Forwarding Detection (BFD) remote IP address here. This IP address must be a real IP address of a real device in the same VRRP virtual group. A BFD session will be created between this VRRP router and its peer. When the session goes down, if the VRRP is in the backup state, it will Switch to master fast. Enter the critical IPv4 address here. If the critical IP is configured on one virtual router, the virtual router cannot be activated when the critical IP address is unreachable. One VRRP group can only track one critical IP. Select to enable or disable the shutdown feature here. This feature is used to disable a virtual router on an interface. Avoid the common mistake of shutting down the IP address owner router before shutting down other non-owner routers. Click the Back button to return to the previous window.
