HP Continuous Access EVA 3-site configurations

This section describes the following HP Continuous Access EVA 3-site configurations:
• "HP Continuous Access EVA 3-site configuration with four
• "HP Continuous Access EVA 3-site configuration with six
• "HP Continuous Access EVA 3-site configuration with eight
• "3-site configuration with six gateways and full inter-site
The first three configurations provide a fan-in or fan-out relationship between the sites. The fourth
configuration provides a peer-to-peer relationship between all sites.
