There are at least two, cisco and Proteon.

However the real advantage of level two bridges like the Vitalink is
that they let you also run ISO, XNS, Ethertalk, Novell and what have
you with no further modification. Given the dynamic state of protocols
today this is a big advantage. For example, the low level protocols
of DECnet will change drastically next year. Proteon and cisco may
or may not keep up, but a level two bridge won't even notice.
