Track port configuration

NOTE

Track port is not supported by VRRP v3.

You can configure the VRID on one interface to track the link state of another interface on the Layer
3 switch. This capability is quite useful for tracking the state of the exit interface for the path for
which the VRID is providing redundancy. Refer to

“Track ports and track priority”

on page 416.

To configure interface 1/1/6 on Router 1 to track interface 1/1/2, enter the following commands.

Brocade Router1(config)#interface ethernet 1/1/6

Brocade Router1(config-if-e10000-1/1/6)#ip vrrp vrid 1

Brocade Router1(config-if-e10000-1/1/6-vrid-1)#track-port ethernet 1/1/2

Syntax: track-port ethernet stack-unit/slotnum/portnum | ve num

The syntax is the same for VRRP and VRRP-E.

Track priority configuration

NOTE

Track priority is not supported by IPv6 VRRP v3.

When you configure a VRID to track the link state of other interfaces, and one of the tracked
interfaces goes down, the software changes the VRRP or VRRP-E priority of the VRID interface:

For VRRP, the software changes the priority of the VRID to the track priority, which typically is
lower than the VRID priority and lower than the VRID priorities configured on the Backups. For
example, if the VRRP interface priority is 100 and a tracked interface with track priority 60
goes down, the software changes the VRRP interface priority to 60.

For VRRP-E, the software reduces the VRID priority by the amount of the priority of the tracked
interface that went down. For example, if the VRRP-E interface priority is 100 and a tracked
interface with track priority 60 goes down, the software changes the VRRP-E interface priority
to 40. If another tracked interface goes down, the software reduces the VRID priority again, by
the amount of the tracked interface track priority.

The default track priority for an Owner for VRRP v2, IPv6 VRRP v3, and VRRP-E v2 and IPv6 VRRP-E
v3 is 2. The default track priority for Backup routers is 1.

You enter the track priority as a value with the owner or backup command. Refer to

“Track port

configuration”

on page 439.

Syntax: owner [track-priority value]

Syntax: backup [priority value] [track-priority value]

The syntax is the same for VRRP and VRRP-E.
