Chapter 39 Device HA

ZyWALL USG 1000 User’s Guide

Here are two ways to avoid a broadcast storm when you connect the bridge 
interfaces on two ZyWALLs.

The first way is to activate device HA before connecting the bridge interfaces as 
shown in the following example.

VRID

Type the virtual router ID number.

Virtual Router 
IP (VRIP) / 
Subnet Mask

This is the interface’s IP address and subnet mask in the virtual router.

Authentication

Select the authentication method used in the virtual router. Every 
interface in a virtual router must use the same authentication method 
and password. Choices are:

None - this virtual router does not use any authentication method.

Text - this virtual router uses a plain text password for authentication. 
Type the password in the field next to the radio button. The password 
can consist of alphanumeric characters, the underscore, and some 
punctuation marks (+-/*= :; .! @$&%#~ ‘ \ () ), and it can be up to 
eight characters long.

IP AH (MD5) - this virtual router uses an encrypted MD5 password for 
authentication. Type the password in the field next to the radio button. 
The password can consist of alphanumeric characters, the underscore, 
and some punctuation marks (+-/*= :; .! @$&%#~ ‘ \ () ), and it can 
be up to eight characters long.

See 

 for more information about 

authentication methods.
