All clients have full connectivity to the servers. For the sake of frame diversity, the environment is not entirely realistic. For instance:
•
NAT and PAT overload are both being used on the Branch network, but the Central 10.X.X.X network is being shared publicly.
•
There is a separate DNS server in the 172 network due to the inability of computers to use the file server's public address. The simulated DNS server, unlike BIND, is basic and does not forward requests that it does not know to a root server - so the A records are duplicated.
•
EIGRP is running in the cloud, as opposed to BGP.
•
The Branch switch is actually providing DHCP, just because it can. It makes that side of the simulation different than the Central side.
•
The cloud includes two servers, one of which uses the correct IP of netacad.com, and the other uses the correct IP of Google's DNS.
•
The router passwords are "cisco" and "class", but there is a "banner motd" and "banner login" which readily give the passwords to the curious.
•
The S1 and S2 switches have spanning tree PVST enabled. Each has a different blocking port, so all connections are green.
