1128 ExtremeWare Software 7.3.0 Command Reference Guide
VRRP Commands
If the master router becomes unavailable, the election process provides dynamic failover and the backup
router that has the highest priority assumes the role of master.
A new master is elected when one of the following things happen:
• VRRP is disabled on the master router.
• Communication is lost between master and backup router(s). The master router sends periodic
advertisements to the backup routers to indicate that it is alive.
VRRP also supports the following tracking options:
• VRRP VLAN tracking
• VRRP route table tracking
• VRRP ping tracking
If a tracking option is enabled, and the object being tracked becomes unreachable, the master device will
fail over. These tracking features are documented in the chapter on ESRP.
VRRP also supports port restart. Like the tracking features, the commands to enable and disable this
feature are described in the chapter on ESRP.
