VRRPv3 Authentication

When VRRPv3 (for IPv4) is enabled, it does not allow authentication.

You must use non-VRRP authentication.

VRRPv3 Advertisement Intervals

VRRPv3 (for IPv4 and IPv6) advertisement intervals must be set with the
statement at the
[edit interfaces interface-name unit 0 family inet address ip-address
vrrp-group group-name] hierarchy level.

Unified ISSU for VRRPv3

Design changes for VRRP unified in-service software upgrade (ISSU) are made in Junos
OS Release 15.1 to achieve the following functionality:
Maintain protocol adjacency with peer routers during unified ISSU. Protocol adjacency
created on peer routers for the router undergoing unified ISSU should not flap, which
means that VRRP on the remote peer router should not flap.
Maintain interoperability with competitive or complementary equipment.
Maintain interoperability with other Junos OS releases and other Juniper Network
products.
The values of the following configurations (found at the
unit 0 family inet address ip-address vrrp-group group-name]
kept at maximum values to support unified ISSU:
On the master router, the advertisement interval (the
to be kept at 40950 milliseconds.
On the backup router, the master-down interval (the
statement) needs to be kept at the largest threshold value.
This VRRP unified ISSU design only works for VRRPv3. It is not supported on VRRPv1 or
VRRPv2. Other limitations include the following:
