This is why Paul's solution, though accurate, will not work in your
scenario.
The fact that you are trying to go across an aggregated link in the
middle between the two buildings where you have no control is going to
hinder you severely.
The only other nasty thing that comes to mind is to assign additional
MAC / IP sets to each system on their second interfaces. Establish
IP-IP (?) tunnels between the two systems via each pair of MAC / IP
sets. I.e. Machine A Primary MAC / IP set to machine B Primary MAC / IP
set and Machine A Secondary MAC / IP set to machine B Secondary MAC / IP
set. Thus yielding two tunnels between the two machines. Then if you
were trying to get to an IP address that could be routed by the IP
address at the end of either tunnel, you could then use something like
Equal Cost Multi Path (a.k.a. ECMP) routing to send packets down both
routes. Seeing as how the traffic you are sending will be encapsulated
in IP-IP tunnel packets, each of which should be between its own MAC /
IP sets, the switch(s) so the switches should not cause a problem by
doing what they are doing.
