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 MPX200 routers
• HP Continuous Access EVA 3-site configuration with six MPX200 routers
• HP Continuous Access EVA 3-site configuration with eight MPX200 routers
• 3-site configuration with six gateways and full inter-site connectivity
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.
Figure 79 shows connectivity for three sites using four MPX200 routers, which implement the
minimum-level and lowest-cost connectivity for a 3-site configuration. Figure 80 shows additional
connectivity and redundancy using six MPX200 routers. Figure 81 shows the highest level of 3-site
connectivity using eight MPX200 routers.
Figure 82 is similar to Figure 80, with additional connectivity to allow for replication between Site 2
and Site 3.
The following configuration rules apply to Figure 79 through Figure 81 (fan-in/fan-out relationships):
• For Site 1, Site 2 or Site 3 can function as the remote site.
• For Site 2 or Site 3, Site 1 can function as the remote site.
• Replication between Site 2 and Site 3 is not supported.
The following configuration rules apply to Figure 82 (peer-to-peer relationship):
• For Site 1, Site 2 or Site 3 can function as the remote site.
• For Site 2, Site 1 or Site 3 can function as the remote site.
• For Site 3, Site 1 or Site 2 can function as the remote site.
