If you include spaces, enclose all characters in quotation marks (" "). The key must be
the same for all routing platforms in the VRRP group.
You can include this statement at the following hierarchy levels:
[edit interfaces interface-name unit logical-unit-number family inet address address
vrrp-group group-id]
[edit logical-systems logical-system-name interfaces interface-name unit
logical-unit-number family inet address address vrrp-group group-id]

Therefore, if authentication is required, you need to configure alternative
non-VRRP authentication mechanisms.

By default, the master router sends VRRP advertisement packets every second to all
members of the VRRP group. These packets indicate that the master router is still
operational. If the master router fails or becomes unreachable, the backup router with
the highest priority value becomes the new master router.
You can modify the advertisement interval in seconds or in milliseconds. The interval
must be the same for all routing platforms in the VRRP group.
For VRRP for IPv6, you must configure IPv6 router advertisements for the interface on
which VRRP is configured to send IPv6 router advertisements for the VRRP group. To do
so, include the
interface interface-name
router-advertisement] hierarchy level. (For information about this statement and
guidelines, see the Junos OS Routing Protocols Library.) When an interface receives an
IPv6 router solicitation message, it sends an IPv6 router advertisement to all VRRP groups
configured on it. In the case of logical systems, IPv6 router advertisements are not sent
to VRRP groups.
