One Network with 2Routers

Hi,
I am trying to create a network with the following characteristics:

  • Two Mikrotik devices, hap ac lite and hap lite
  • One (hap ac lite) is connected to the modem, the other is connected to the hap ac lite via ethernet
  • Create one large Network, i.e. connected devices to any part of the network (wireless, ethernet port from either router) can talk to each other
  • The hap ac lite is the CAPsMAN, the other is a CAP
  • DHCP by the CAPsMAN
  • Static IP adress for the CAP
  • Static IP adress for one device connected to the CAP (hap lite)

So far I have the hap ac lite as my CAPsMAN. It is managing both its own wlan as well as the CAPs wlan centrally via 1 conifg (awesome). However it seems that when I connect something to the ethernet port of my CAP, it is not automatically in the network created by the CAPsMAN. Can I somehow bridge (or sth else appropriate) these two ethernet parts of the routers into one network?
Furthermore I have also not been able to give static IP adresses to the CAP as well as the device connected to the ethernet port at the CAP.
Please let me know if any further information is needed (configuration?) to help with this.

Thank you for your help.
