Figure 22: Fully Meshed WAN Connections - Deployment Example
In a multi-node installation, it is also possible to link a single VPN back to headquarters at
another site using a star configuration. If the WAN network router (Service Provider Router;
see Figure 23) at the HQ site can perform routing between the different sites, this is equivalent
to a fully meshed network, since the network router will re-direct the data and not use bandwidth
back to the headquarter site.
This star configuration can still be described by Table 52, and is illustrated in Figure 23. The
number of routes within the WAN are reduced, but from the end user view, this configuration
behaves in the same manner as the fully meshed configuration. The only consideration for this
star configuration is that the central router will be dealing with all internode traffic, and must
have the necessary performance to handle the bandwidth and packet rate expected within the
WAN connections.
