Introduction
 • Transmit IP multicast packets as single route explorer packets.
 • Transmit subnet-specific broadcasts as single route explorer 
packets.
1.8.5  Configuring IP Routing Over Source Routing
The IP routing over source-routing feature is integrated with the 
multiple IP networks per ATX port feature. Configuration is 
specified for each binding of an IP subnet.
 • No source-routing - ARP requests are sent as transparent 
explorer packet. This is normal for non-Token Ring LANs.
 • Source-routing - ARP requests are transmitted as source-routing 
explorer packets. This is the default for most TCP/IP 
implementations on a Token Ring LAN.
 • Both transparent and source-routing - Two ARP requests are 
transmitted; one transparent and one explorer. This provides the 
best connectivity where it is not known whether the intended 
destination is capable of source-routing.
 • Default - If the port is Token Ring, both types of ARP requests 
are transmitted. For other LAN types, ARP requests are sent as 
transparent frames.
Configuration is provided by the 
sipckt
 
portion of the Cabletron 
proprietary MIB. The 
sipNetToMedia 
Table, within the 
Cabletron proprietary MIB, allows you to manage the source route 
as part of the ARP cache. See the ATX MIB Reference Guide for 
information on 
sipckt
 and the 
sipNetToMedia
 Table.
1.8.6  IPX Routing
The ATX can route Internetwork Packet Exchange (IPX) packets. 
IPX is Novell’s protocol that allows users in a Netware 
internetwork to communicate. The ATX identifies IPX packets and 
routes them appropriately.
