displays the major components to configure a VRRP instance in an IES service.

Figure 17: IES VRRP Configuration Components

IES — The context to creates or modify an IES service.

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.
