connectivity and redundancy using six mpx110 gateways. Figure 105 shows the highest level of
3-site connectivity using eight mpx110 gateways.
The following configuration rules apply to Figure 103 through Figure 105 (fan-in/fan-out):
• 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.
Figure 106 (page 281) is similar to Figure 104 (page 279), with additional connectivity to allow for
replication between Site 2 and Site 3.
The following configuration rules apply to Figure 106 (page 281) (peer-to-peer):
• 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.
Figure 103 (page 278) shows long-distance link redundancy between all three sites.

Figure 104 (page 279) shows the same long-distance link redundancy as Figure 103 (page 278),
with the addition of redundant mpx110 gateways at Sites 2 and 3.
