JUNOSe 11.1.x Service Availability Configuration Guide
NOTE: If you configure VRRP on a virtual router and associate the IP address with
the VRRP instance ID (VRID) so that the virtual address becomes the interface address
of the router, the priority of the router automatically changes to 255 making it the
master router. This change of priority occurs in JUNOSe Software Releases 11.0.0
and higher-numbered releases and later to enable full compliance with RFC-Virtual
Router Redundancy Protocol (VRRP) (April 2004).
Also, you cannot configure the priority of the VRRP router as 255 by using the ip
vrrp priority command, unless you configured the router to automatically learn
associated addresses by using the auto keyword with the ip vrrp virtual-address
command. In addition, if you change the virtual address of the VRRP router, which
is operating as the IP address owner, to an IP address that is no longer the IP address
owner, the priority changes automatically to the default value of 100.

Configuring VRRP
(Optional) Set the VRRP authentication type to either text or none.
host1(config-if)#ip vrrp 25 authentication-type none
(Optional) Configure the VRRP authentication key.
host1(config-if)#ip vrrp 25 authentication-key dublin
Enable the VRID instance.
host1(config-if)#ip vrrp 25 enable
Use to create a VRID instance.
The VRID range is 1–255.
Example
host1(config-if)#ip vrrp 25
Use the no version to remove a VRID instance.
See ip vrrp.
Use to enable the backup router to process packets with an IP destination address
equivalent to the virtual addresses while the backup router is in the master state.
Use the default state (disabled) for full compliance with RFC 3768.
The configuration ignores this attribute if the VRRP entry uses a priority of 255
(owner).
