Hello
I will be building out a new infrastructure as we will be implementing MPLS via AT&T service, with two sites in CA, one in CO. AT&T will provide Internet connection at one site in CA (main site) and the CO site. I would like to also use a FE/BE Exchange setup with proper firewalls in place. I will put FE/BE at both CA (main) site and CO site. Failover and redundancy is obsolutely critical between all three sites- business critical are Exchange and Internet. Cost is not primary or secondary issue.
I would like to see what the basic network and hardware diagram would look like- placement of firewalls/routers, and how or if I can use AT&T's "managed" router. (dual WAN ports?) We will have a PT-PT T1 between the two CA sites.
If more information is needed, I will provide. Thanks in advance.
