We can extend the idea of distributed console server hosts in our earlier
security models. In this case, all of the logging traffic is kept on the remote
management network, as peer-to-peer traffic, and only the client sessions from
other sites is carried over the tunnel. This is, in essence, the architecture used
by Synopsys in their field offices
It is possible to have console clients in the remote office, even though it was
not shown on the diagram above. With a single configuration file, a client on
the remote MGMT network would connect to the console server on the same
local network, and it could be redirected to other console server hosts if the
client wanted to connect to console devices hosted on other networks.
