Command Usage
• The interfaces of all routers participating in a virtual router group mus t be
within the same IP subnet.
• If the IP address assigned to the virtual router with this command is already
configured as the primary address on this interface, this router is considered
the Owner, and will assume the role of the Master virtual router in the gr oup.
• This interface is used for two purposes - to send/receive a dvertisem ent
messages and to forward on behalf of the virtual router when operating as the
Master VRRP router.
• VRRP is enabled as soon as this command is entered. If you need to
customize any of the other parameters for VRRP such as authenticat ion,
priority, or advertisement interval, then first configure these parameters before
enabling VRRP.
