Zigbee Network Map - Red Dashed Lines?

Hello, do anyone know what is the dashed red lines that comes out from my Aqara Relays to the Zigbee Router 1 that was recently added to my network (cc2530+2591)?

These ?

For the legend, I’m sorry, It’s red and with dashes when relationship > 3 . What does that mean? I don’t know. I simply reproduced this logic on Z2M. It’s something coming directly from ZStack in Herdsman.

Relationship values are defined as:

0: Neighbour is the parent
1: Neighbour is a child
2: Neighbour is a sibling (has same parent)
3: None of the above
4: Neighbour is a former child
