VRRP Tracking Commands

This section provides information about the VRRP tracking commands. The configuration of VRRP tracking is accomplished with two logical steps.

1. Configure the events that can impact VRRP priority change by defining tracking objects.

2. Link between VRRP priority changes and tracking objects by specifying VRRP priority change for state change in the tracked objects.

track

A track object can track a particular interface property or IP layer properties. An interface might be tracked by its line-protocol state (up/down) or by its IP routing state (enable/disable). Use the following commands according to the tracking method you prefer.

track <object-number> interface <unit/port> line-protocol

Track the link state of an interface. This object will be up when the interface is linked.

• Default - none
• Format - track <object-number> interface <unit/port> line-protocol

track <object-number> interface <unit/port> ip routing

Tracks the state of a local IP route.

• Default - none
• Format - track <object-number> interface <unit/port> ip routing
• Mode - Global Config

An IP-routing object is considered up when the following criteria exists:

• IP routing is enabled and active on the interface.
• The interface line-protocol state is up.
• The interface IP address is known. The IP address is configured or received through the Dynamic Host Configuration Protocol (DHCP) or IP Control Protocol (IPCP) negotiation.

An IP-routing object is considered down when one of the following criteria exist:

• IP routing is disabled globally.
• The interface line-protocol state is down.
• The interface IP address is unknown. The IP address is not configured or received through DHCP or IPCP negotiation.

track <object-number> ip route <ip-address/prefix-length> reachability

Tracks the state of a remote IP address. This object will be up when the remote IP address is present in the ARP table.

• Default - none
• Format - track <object-number> ip route <ip-address/prefix-length> reachability
• Mode - Global Config

no track

Removes the track with the given object number.

• Format - no track <object number>
• Mode - Global Config

vrrp

• Mode - Global Config

no vrrp

Removes the specified track object from the specificed VRRP instance.

Router Id	A 4-digit dotted-decimal number identifying neighbor router.
Options	An integer value that indicates the optional OSPF capabilities supported by the neighbor. The neighbor's optional OSPF capabilities are also listed in its Hello packets. This enables received Hello Packets to be rejected (i.e., neighbor relationships will not even start to form) if there is a mismatch in certain crucial OSPF capabilities.
Router Priority	Displays the OSPF priority for the specified interface. The priority of an interface is a priority integer from 0 to 255. A value of '0' indicates that the router is not eligible to become the designated router on this network.
State	The types are: Down - initial state of the neighbor conversation - no recent information has been received from the neighbor. Attempt - no recent information has been received from the neighbor but a more conAcerted effort should be made to contact the neighbor. Init - an Hello packet has recently been seen from the neighbor, but bi-directional communication has not yet been established. 2 way - communication between the two routers is bi-directional. Exchange start - the first step in creating an adjacency between the two neighboring routers, the goal is to decide which router is the master and to decide upon the initial DD sequence number. Exchange - the router is describing its entire link state database by sending Database Description packets to the neighbor. Loading - Link State Request packets are sent to the neighbor asking for the more recent LSAs that have been discovered (but not yet received) in the Exchange state. Full - the neighboring routers are fully adjacent and they will now appear in router- LSAs and network-LSAs.
Events	The number of times this neighbor relationship has changed state, or an error has occurred.
