Are some of my bulbs routers?

Just got Zigbee2mqtt running with my openHAB system, and it works great. I paired a few lights, and decided to set up an extra router because I have a large house.

I did a network map command in Zigbee2mqtt and the results surprised me. 2 of my bulbs have the same graphviz decoration as my new router; does that mean those 2 bulbs act as mesh routers for Zigbee?

Thanks,

Steven

In theory, all mains powered ZigBee devices are routers. However, there are some exceptions, but in your case: yes they are routers.
