As previously mentioned, the Bacnet network maintains a table of BACnet routers, in the BacnetComm, Network component. Included is the ability to modify, add, or remove entries representing BACnet routers. See About Bacnet Comm: Network: Router Table.

Typically you should not need to edit this table, which is automatically populated when you perform a Discover from the Bacnet network, or perform a “Who Has” command.
