z
Count IP Addrs: Number of virtual IP addresses for the standby group. A standby
group can have multiple virtual IP addresses.
z
Auth Type: Authentication type. 0 means no authentication, 1 means simple
authentication, and 2 means MD5 authentication.
z
Adver Int: Interval for sending advertisement packets, in seconds. The default is 1.
z
Checksum: 16-bit checksum for validating the data in VRRP packets.
z
IP Address: Virtual IP address entry of the standby group. The allowed number is
given by the Count IP Addrs field.
z
Authentication Data: Authentication key. Currently, this field is used only for simple
authentication and is 0 for any other authentication modes.

IPv6-based VRRP packet format
As shown in
, an IPv6-based VRRP packet consists of the following fields:
z
Version: Version number of the protocol, 3 for VRRPv3.
z
Type: Type of the VRRP packet. Only one VRRP packet type is present, that is,
VRRP advertisement, which is represented by 1.
z
Virtual Rtr ID (VRID): Number of the virtual router, that is, number of the standby
group. It ranges from 1 to 255.
z
Priority: Priority of the switch in the standby group, in the range 0 to 255. A greater
value represents a higher priority.
z
Count IPv6 Addrs: Number of virtual IPv6 addresses for the standby group. A
standby group can have multiple virtual IPv6 addresses.
