Hi all,

I hope someone can advise, before I make an almighty cock-up. We've decided
to install a gigbit backbone for the servers to communicate on. Internally,
we use 172.20.0.1 - 31 for the servers, 33 and up for network devices, and
172.20.1.0 - 254 for workstations. All devices on the network are using
255.255.0.0 as a net mask. My cunning plan was to put 1gb cards in all the
servers, and assign the same IP to each of the cards on the backbone, as is
assigned on the client-visible side. The firewall would be configured with
a third interface with the IP 172.20.0.31/26 connected to the backbone.
Would it need to have a static route added to force traffic for the servers
to come over the server backbone ?

Each server would have their default gateway set against the new card to be
172.20.0.31. Could I rely on the IP stacks of the servers (Aix5.2, Linux
2.4, Win2k, Win2k+3) to setup their routing tables such that when
attempting to talk to a neighbouring server, they use their private
network, without having a complete brain fart ? Would I have to tweak the
metric values, such that the client-visible cards had a greater metric
value than the private-server side ?

Hope this makes sense, and TIA

Kind regards

Simon Delicata
