Item Descri

tion

Priority

Set the priority of the routers in a VRRP group. The greater the value, the higher the

priority.

IMPORTANT:

• VRRP determines the role (master or backup) of each router in the VRRP group by

priority. A router with a higher priority has more opportunity to become the

master.

• VRRP priority is in the range of 0 to 255. Priority 0 is reserved for special uses and

priority 255 for the IP address owner.

• When a router acts as the IP address owner, its priority is always 255. That is, the

IP address owner in a VRRP group acts as the master as long as it works properly.

Preempt Mode

Set the working mode of the VRRP group.

• Preemptive: preemptive mode.

• Non-preemptive: non-preemptive mode.

Delay

Set the VRRP preemption delay timer when the VRRP group works in the preemptive

mode.

This item is configurable when you set the preempt mode to Preemptive.

Authentication

Set the authentication mode and authentication key of the VRRP group.

• Null: no authentication and no authentication key.

• Simple: simple text authentication. In this case, you must configure a plain text

authentication key.

• MD5: MD5 authentication. In this case, you must configure a plain text

authentication key or an MD5 cipher text authentication key.

IMPORTANT:

You can configure different authentication modes and authentication keys for the VRRP

groups on an interface. However, the members of the same VRRP group must use the

same authentication mode and authentication key.

Key

Advertise Time

Set the interval at which the master sends VRRP advertisements.

IMPORTANT:

Routers in the same VRRP group must use the same setting of advertisement interval.
