Does anyone know of a bridge or router that will allow HP hosts running
TCP/IP which speak IEEE style packets (802.2 encapsulated) to
communicate with ethernet style IP implementations? Do most of the
router/bridge vendors support both IEEE and ethernet style IP packets?
Thanks in advance
Kevin

The cisco router will do this and has for the last three year. Drop a note to customer-service@cisco.com for more information. Greg

I've answered Kevin separately, but here is the info for everyone
else:
1. The old-style HP 802.2/802.3 encapsulation pre-dates SNAP. It
uses the SAP originally reserved for IP (06) and uses a separate
protocol for address resolution (Probe). All this design was
done back in 1981-82, when no one but the 802 committee and HP
were interested in 802.
2. HP does not encourage new implementations of HP 802 and Probe,
because there are standard, and thus better, alternatives.
3. All HP products now support Ethernet and ARP, so no one has to
worry about the HP 802 encapsulation anymore. Just upgrade to
the latest networking bits.

I don't have much experience here, but I'm installing a small ethernet network (about a dozen hosts) here at work - and I'm learning while doing. My design includes a bridge in each lab, primarily to aid in fault isolation. The bridge I've chosen is the Retix 2255. The manual says it will pass both style packets transparently, which (I think) answers your second question. It also states that the software on each respective host must deal with packet differences themselves, which (I think) answers your first question (that is, if I understand your first question correctly - you're looking for a bridge that will convert one style packet to another - right? This bridge explicitly *won't* [and I don't know of one that will]. But, it will pass both types, no problem). I hope this helps. -- Bruce Wehr (wehr%dptc.decnet@srlvx0.srl.ford.com) (...uunet!mailrus!sharkey!fmeed1!wehr) (wehr%fmeed1.uucp@mailgw.cc.umich.edu) Ford Motor Company - Electronics Division 17000 Rotunda Drive, ETC Room LN081, Dearborn, Michigan 48121 (313)845-3039
