xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Figure 4- 108. VRRP Virtual Router Settings - Add window Or, the user may click the hyperlinked Interface Name to view the same window: The following parameters may be set to configure an existing or new VRRP interface. Parameter Description Interface Name Enter the name of a previously configured IP interface for which to create a VRRP entry. This IP interface must be assigned to a VLAN on the Switch. VRID (1-255) IP Address State Enter a value between 1 and 255 to uniquely identify this VRRP group on the Switch. All routers participating in this group must be assigned the same VRID value. This value MUST be different from other VRRP groups set on the Switch. Enter the IP address that will be assigned to the VRRP router. This IP address is also the default gateway that will be statically assigned to end hosts and must be set for all routers that participate in this group. Used to enable and disable the VRRP IP interface on the Switch. Priority (1-254) Enter a value between 1 and 254 to indicate the router priority. The VRRP Priority value may determine if a higher priority VRRP router overrides a lower priority VRRP router. A higher priority will increase the probability that this router will become the Master router of the group. A lower priority will increase the probability that this router will become the backup router. VRRP routers that are assigned the same priority value will elect the highest physical IP address as the Master router. The default value is 100. (The value of 255 is reserved for the router that owns the IP address associated with the virtual router and is therefore set automatically.) Advertisement Interval (1-255) Preempt Mode Critical IP Address Enter a time interval value, in seconds, for sending VRRP message packets. This value must be consistent with all participating routers. The default is 1 second. This entry will determine the behavior of backup routers within the VRRP group by controlling whether a higher priority backup router will preempt a lower priority Master router. A True entry, along with having the backup router's priority set higher than the masters priority, will set the backup router as the Master router. A False entry will disable the backup router from becoming the Master router. This setting must be consistent with all routers participating within the same VRRP group. The default setting is True. Enter the IP address of the physical device that will provide the most direct route to the Internet or other critical network connections from this virtual router. This must be a real IP 254
