Subject: Exchange 2000 Routing

All,

We have a fully meshed network (IP Cloud) connecting 65 offices around the
world. We are currently in the process of moving from 5.5 to 2000. We have 3
main HUB sites (Chicago, London, Hong Kong). The hubs have the biggest pipes
into the cloud (Chicago - 4MB, London 2MB, Hong Kong 2MB). All other offices
range from 65K to 512K. Looking for ideas on how to setup the SMTP
connectors between the routing groups (each office, including the hubs - are
in their own routing group. 2 ideas so far 1. 3 Hubs meshed with SMTP
connectors - each remote office with 3 SMTP connectors - 1 connector with
the lowest cost going to Chicago, and then the other 2 connectors with a
higher cost to London and Hong Kong (this would force all traffic through
Chicago which has the biggest pipe and have London and Hong Kong for
redundant paths.
2. 3 Hubs meshed with SMTP connectors - each remote office with 3 SMTP
connectors - 1 connector with the lowest cost going to its respective hub
site (example - Dallas office to Chicago, Paris to London)... and then 2
connectors with a higher cost to London and Hong Kong. 

Our WAN team wants us to create a routing topology so that any office can
send email directly to any other office - this would require over 4000
connectors.

Any thoughts?

TIA,
