There are several articles on the web explaining the differences between a L2 and a L3 switch.
A L3 switch may also act as a router.
Normally, a router does not forward any multicast traffic between the different IP subnets it connects.
RNRP relies on that the multicasted telegrams it emit reaches all nodes of an RNRP Area (=IP subnet).
Depending on what you had in mind with the L3 switch, it may or may not work for System 800xA.

RNRP can act as a router between different RNRP Areas in:
- a computer with at least two network cards and running the ABB RNRP Windows Service
- ABB NE87x RNRP Router. The NE870 has 11 network interfaces while the smaller NE871 offers 3.
