NETGEAR M4500 Series Switches CLI Command Reference Manual 725
When the tracked interface is down or the interface has been removed from the router, the priority of the VRRP
router will be decremented by the value specified in the decrement argument. When the interface is up for IP
protocol, the priority will be incremented by the decrement value.
A VRRP configured interface can track more than one interface. When a tracked interface goes down, then the
priority of the router will be decreased by 10 (the default priority decrement) for each downed interface. The
default priority decrement is changed using the decrement argument. The default priority of the virtual router is
100, and the default decrement priority is 10. By default, no interfaces are tracked. If you specify just the
interface to be tracked, without giving the optional priority, then the default priority will be set. The default
priority decrement is 10.
To remove the interface from the tracked list or to restore the priority decrement to its default, use the no form
of this command.
Format ip vrrp <1-255> track interface {<slot/port> | vlan <vlan-id>} [decrement <1-254>]
no ip vrrp <1-255> track interface {<slot/port> | vlan <vlan-id>} [decrement]
Default Decrement: 10
Mode Interface Config
6.8.2.12. ip vrrp track ip route
This command tracks the route reachability. When the tracked route is deleted, the priority of the
VRRP router will be decremented by the value specified in the decrement argument. When the tracked
route is added, the priority will be incremented by the same.
A VRRP configured interface can track more than one route. When a tracked route goes down, then
the priority of the router will be decreased by 10 (the default priority decrement) for each downed
route. By default no routes are tracked. If you specify just the route to be tracked, without giving the
optional priority, then the default priority will be set. The default priority decrement is 10. The default
priority decrement is changed using the decrement argument.
To remove the route from the tracked list or to restore the priority decrement to its default, use the no
form of this command. When removing a tracked IP route from the tracked list, the priority should be
incremented by the decrement value if the route is not reachable.
Format ip vrrp <1-255> track ip route <ip-address/prefix-length> [decrement <1-254>]
no ip vrrp <1-255> track ip route <ip-address/prefix-length> [decrement]
