NLSP Configuration
NLSP is enabled by the ipx router nlsp command. An area-address command sets network
numbers of the current NLSP area. Each interface is also configured to use NLSP with the ipx
nlsp enable command.

Example 12-7 shows an example of NLSP configuration. An internal network address is
assigned to the router with the ipx internal-network command. Each interface is enabled for
NLSP routing with the ipx nlsp enable command. In Example 12-7, IPX RIP is disabled with
the no ipx router rip command. An area address is assigned to the router with the area-address
command.

IPX EIGRP

Using Enhanced Interior Gateway Routing Protocol (EIGRP) on IPX networks provides fast
rerouting and partial update capabilities that IPX RIP does not provide. EIGRP has several
capabilities that are designed to facilitate large Novell networks that use IPX:
•

Supports incremental SAP updates and route updates only when changes occur

•

Increases the network to 224 hops, from the IPX RIP limit of 15 hops

•

Provides for optimal path selection by using EIGRP metrics versus the IPX RIP ticks and
hop count metric

IPX EIGRP is usually configured on serial links with IPX RIP over the local LAN. IPX RIP is
configured to not broadcast on the interfaces running IPX EIGRP. Example 12-8 shows an
example of the configuration of IPX EIGRP. Each interface is configured with the ipx network
