Cisco Cisco MeetingPlace Gateway SIM Anleitung Für Quick Setup

You can deploy two Application Servers as part of one logical site. Database replication enables the 
Application Servers to synchronize user profiles, user groups, and meeting data. Only one Application 
Server is active at any time. If the active server fails, then you can activate the standby server and place 
the previously active server in standby mode. Each Application Server in a site is called a node. 

If the site includes two Media Servers, then one Media Server will be associated with each Application 
Server. If the site includes only one Media Server, then it is always associated with the active 
Application Server. 

In a failover deployment, each Application Server is configured with two IP addresses—one for each of 
the following interfaces:

eth0—Physical network interface

Assign the same shared hostname and IP address to eth0 on both Application Servers.

Anyone who tries to access the shared hostname or IP address will reach the active Application 
Server.

The eth0 interface is disabled on the standby Application Server.

eth0:0—Virtual network interface

Assign a unique hostname and IP address to eth0:0 on each Application Server.

Use the eth0:0 hostname or IP address to access an Application Server that is in standby mode. 

The system uses the eth0:0 virtual network interface for database replication between the two 
nodes.
