• When an interface comes up and becomes operational, the system waits 300 seconds (5 minutes) to bring up VRRP on that interface. To set the delay time for VRRP initialization, use the following commands. • Set the delay time for VRRP initialization on an individual interface. INTERFACE mode vrrp delay minimum seconds This time is the gap between an interface coming up and being operational, and VRRP enabling. The seconds range is from 0 to 900. The default is 0. • Set the delay time for VRRP initialization on all the interfaces in the system configured for VRRP. INTERFACE mode vrrp delay reload seconds This time is the gap between system boot up completion and VRRP enabling. The seconds range is from 0 to 900. The default is 0. Track an Interface or Object You can set Dell Networking OS to monitor the state of any interface according to the virtual group. Each VRRP group can track up to 12 interfaces and up to 20 additional objects, which may affect the priority of the VRRP group. If the tracked interface goes down, the VRRP group's priority decreases by a default value of 10 (also known as cost). If the tracked interface's state goes up, the VRRP group's priority increases by 10. The lowered priority of the VRRP group may trigger an election. As the Master/Backup VRRP routers are selected based on the VRRP group's priority, tracking features ensure that the best VRRP router is the Master for that group. The sum of all the costs of all the tracked interfaces must be less than the configured priority on the VRRP group. If the VRRP group is configured as Owner router (priority 255), tracking for that group is disabled, irrespective of the state of the tracked interfaces. The priority of the owner group always remains at 255. For a virtual group, you can track the line-protocol state or the routing status of any of the following interfaces with the interface interface parameter: • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port. • For a 40-Gigabit Ethernet: enter fortyGigE slot/port. • For a port extender 1-Gigabit Ethernet interface, enter the keyword peGigE then the pe-id/stack- unit-number/port-number. • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094. For a virtual group, you can also track the status of a configured object (the track object-id command) by entering its object number. 1124 Virtual Router Redundancy Protocol (VRRP)
