Re: IPX - multiple frame encapsulations on one wire

Sam,

You can't use secondary addresses with IPX on a Cisco router this way. You hav
e to use sub-interfaces.

Interesting side note here. While you can't do this on a Cisco router, a NetWa
re server of any relatively recent vintage has no problem doing this whatsoever
.

I've seen absolutely horrific broadcast storms at customer sites where the serv
ers where bound to two frame types (802.2 and 802.3) and were routing between t
he two 'different' networks on the same NIC. If you load the IPXRTR.NLM with t
he option 'routing=none', it defeats this behavior.

ally come in handy!)
