Using BAC0 to see MSTP network via Bacnet Router (Siemens PXG3.M)

[sourcebitt]

When using BAC0.lite(), then bacnet.discover(networks='1600'), I see the Siemens router with all it's bacnet info. I do not see any MSTP devices that are connected to this router. If I use YABE, it sees all of the devices - router and the MSTP.
Is there a way for me to see these devices through BAC0?

I have located my error. When srtarting BAC0.lite(), I have to define IP address and subnet mask since my subnet mask is /22 instead of default that is used by bacpypes.
bacnet = BAC0.lite(ip='xxx.xxx.xxx.xxx/22')
