VRRP Configuration Process Overview

Figure 16: Interface VRRP Configuration Components
• Interface — A logical IP routing interface.
• Address — Assigns the primary IP address for the interface. A primary IP address must be
assigned to each IP interface.
• Secondary — Assigns a secondary IP address, IP subnet/broadcast address format to the
interface.
• VRRP — The context to configure a VRRP virtual router instance. A virtual router is
defined by its VRID and a set of IP addresses.
• Owner — When the
owner keyword is specified, the virtual router instance owns the
backed up IP addresses. Only one router in the message domain can be the owner.
•Non-owner
— VRRP instances are created as non-owners unless the owner keyword is
specified. Non-owners are all the other virtual router instances participating in the message
domain that have the same VRID configured.
• Backup — Non-owner virtual router instances create a routable IP interface address that is
operationally dependent on the virtual router instance mode (master or backup). The
backup command in
owner virtual router instances does not create a routable IP interface
address; it defines the already existing parental IP interface IP addresses that are advertised
by the virtual router instance.
For
owner virtual router instances, backup defines the list of IP addresses that will be
advertised within VRRP Advertisement messages. This indicates to backup virtual routers
receiving the messages what IP addresses the master is representing.
• Policy — (optional) Assigns an existing VRRP priority control policy association with the
virtual router instance.
