Introduction The TXPORT MultiPro series products can be optioned to be IPX routers with the
addition of the LAN interface card. The model 9101 comes standard with the
router option while models 9000, 9111, and 9211 have an option that can be
ordered.
With the addition of the routing capabilities, MultiPro series products can fully
integrate LAN traffic with the legacy traffic residing on your network. The IPX
router can handle small office networks as well as larger environments.
The router option allows flexibility in network design. The router can be used for a
leased line application as well as in standard frame relay networks.
TXPORT
IPX Router
Protocols The TXPORT IPX Router supports IPX, RIP, SAP and NLSP protocols which are
described in the following paragraphs.
Internetwork Packet
Exchange (IPX)
Summary
Description
IPX is a Novell adaptation of the Xerox Network System’s (XNS) Internet
Datagram Protocol (IDP). IPX is datagram driven, it is a connectionless protocol
that does not require an acknowledgment for each packet being sent on the
network. All acknowledgment and connection control must be provided by
protocols above IPX.
The TXPORT router supports IPX RIP and IPX SAP type packets. This allows
addressing, routing, and switching information packets from one location to
another on an internetwork.
Routing Information
Protocol (RIP)
Summary
Description
Like IPX, RIP has been derived from XNS. But IPX is significantly different so
direct applications of XNS RIP cannot be used. The Routing Information Protocol
facilitates the exchange of Routing Information on the NetWare internetwork.
Here is an idea of how RIP works: RIP packets are exchanged between
neighboring routers. When a router becomes aware of any change in the
internetwork layout, the information is immediately broadcasted to any
neighboring routers. RIPs are also sent periodically to verify that all information is
synchronized. RIP also allows any workstations to locate the fastest route to a
distant network.
