[FROG] FRRouting and MPLS

Hello, I have just installed FRR for the first time on a Linux CentOS 8 distribution. I am therefore just starting out. I am gradually reading the forums but there is a lot of information. FRR manages without worries the BGP and the ISIS which I use regularly on my cisco routers. I am now trying to find out if FRR can integrate more deeply into my network, particularly at the MPLS level. as I understood it is in the Kernel that this is done and not in FRR, but is there a way to integrate VRF IP VPN? and the creation of a VLAN type subinterface directly in FRR? Then last question: Is there an implementation of the Cisco EoMPLS equivalent in FRR? (xconnect encapsultation mpls) thank you Olivier
