The 8209 is IBM's "High Performance" bridge.  It can be configured with
two token ring cards or a token ring and an ethernet card and bridge 
between them.

A bridge transparently moves packets from one network to another at the 
Data-link level. (Ethernet/token ring address)

Higher levels (DECNET,SNA,NETBIOS,IP, etc) are uneffected and usually
don't even know (or care) about the bridge.
