When routing TCP/IP to a bridged token ring network with Ethernets attached via IBM 8209s, accessibility problems result in the following situation: 1. The target station is resident on the Ethernet. 2. The AGS Gateway contains a valid IP ARP cache entry for the target station. 3. The token ring source routing RIF cache entry for the station has been aged out. To find the best route, an XID explorer frame is sent to the target station and the 8209 bridges it to the Ethernet. However, most Ethernet V2 stations don't respond to XID frames. Consequently, the station cannot be accessed. A solution is to hard configure the Ethernet station as having a permanent RIF but this is not very flexible. In the other direction, everything works fine. Is there a fix available? Has anybody else experienced this problem?
