DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide Parameter Virtual IP Address Advertisement Interval Preemption Priority Critical IP Address Non-owner ping Shutdown Description Enter the virtual IPv4/IPv6 address here. This parameter will be either IPv4 or IPv6 depending on the Address Family selection made in the previous step. All routers in the same VRRP group must be configured with the same virtual router ID and virtual address. The IP address of the virtual router can be a real address configured on the routers or an unused address. If the virtual address is equal to the real address of the interface, this virtual router is the IP address owner. Enter the time interval value between successive advertisements by the master router here. The range is from 1 to 255 seconds. The master will constantly send VRRP advertisements. All virtual routers in a VRRP group must use the same timer values. Select to enable or disable the preemption feature here. This 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 of the virtual router here. The range is from 1 to 254. The master of a VRRP group is elected based on the priority. The virtual router with the highest priority becomes the master and others with lower priorities act as the backup for the VRRP group. If there are multiple routers with the same highest priority value, the router with the larger IP address will become the Master. The router that is the IP address owner of the VRRP group is always the master of the VRRP group, and has the highest priority of 255. Enter the critical IP 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 address. Select to enable or disable the non-owner ping feature here. This is used to enable a non-IP address owner virtual router in the master state to response the ICMP echo request for IPv4 addresses or the ND request for IPv6 addresses. Select to enable or disable the shutdown feature here. Avoid the common mistake of shutting down the IP address owner routers before shutting down other nonowner routers.
