Hello Phil,
I just wanted to follow up on this item.
Just to clarify, we don't want to create a single large BACnet network across all sites, because this could create BACnet Address conflicts (adding a new device to site A it could cause a conflict with an existing device on site X). There are also traffic issues that could be caused by having every broadcast request being sent to all devices across all sites. The other option of having segregated BACnet network addresses (BAC0, BAC1...) isn't reasonable, because this would cause logistical configuration headaches at each site for device configuration without any tangible benefits that can't be already achieved by isolating the site as a LAN.
As you had mentioned on your initial response, there could be an issue in having multiple BBMD addresses in a single communication path, because you'd run into a similar situation of having ambiguous device addresses, etc.
Normally BBMD seems to be configured when setting up the route that you would use to talk to a device/site/LAN. However, when trying to do this with local BACnet I'm running into issues with available IP addresses for the local bind address. I've been able to use 0.0.0.0 and 172.10.10.2. Other IP addresses create bind errors though (since Mango isn't able to bind to an unknown IP). Are there any other suggestions/paths or approaches that I should take to try to configure these sites in Mango?
Thanks again for your assistance.
