Tracked Ports And Track Priority With Vrrp And Vrrp-E - Brocade Communications Systems ICX 7250 Series Configuration Manual

Tracked ports and track priority with VRRP and VRRP-E

5. Assign the same VRID as the VRID used by the owner device.
device(config-if-e1000-1/1/5)# ip vrrp vrid 1
NOTE
You can assign a VRID number in the range of 1 through 255.
6. Designate this router as a backup VRRP device.
device(config-if-e1000-1/1/5-vrid-1)# backup priority 110
While configuring a backup device, you can set a priority that is used when a master VRRP device goes offline. The backup
device with the highest priority will assume the role of master device.
7. Set the VRRP version to 3 to indicate that this is VRRPv3 session for IPv4.
device(config-if-e1000-1/1/5-vrid-1)# version 3
8. Configure the IP address of the VRID.
device(config-if-e1000-1/1/5-vrid-1)# ip-address 10.53.5.1
The VRID IP address is the same virtual IP address that you used for the VRRP owner device.
9. Enable the VRRP session.
device(config-if-e1000-1/1/5-vrid-1)# activate
VRRP router 1 for this interface is activating
The following example configures a VRRP owner device.
device# configure terminal
device(config)# router vrrp
device(config)# interface ethernet 1/1/5
device(config-if-e1000-1/1/5)# ip address 10.53.5.3/24
device(config-if-e1000-1/1/5)# ip vrrp vrid 1
device(config-if-e1000-1/1/5-vrid-1)# backup priority 110
device(config-if-e1000-1/1/5-vrid-1)# version 3
device(config-if-e1000-1/1/5-vrid-1)# ip-address 10.53.5.1
device(config-if-e1000-1/1/5-vrid-1)# activate
VRRP router 1 for this interface is activating
Tracked ports and track priority with VRRP and
VRRP-E
Port tracking allows interfaces not configured for VRRP or VRRP-E to be monitored for link-state changes that can result in dynamic
changes to the VRRP device priority.
A tracked port allows you to monitor the state of the interfaces on the other end of a route path. A tracked interface also allows the virtual
router to lower its priority if the exit path interface goes down, allowing another virtual router in the same VRRP (or VRRP-E) group to
take over. When a tracked interface returns to an up state, the configured track priority is added to the current virtual router priority value.
The following conditions and limitations exist for tracked ports:
• Track priorities must be lower than VRRP or VRRP-E priorities.
• The dynamic change of router priority can trigger a master device switchover if preemption is enabled. However, if the router is
an owner, the master device switchover will not occur.
• The maximum number of interfaces that can be tracked for a virtual router is 16.
• Port tracking is allowed for physical interfaces and port channels.
