2501C

In the 2501C router, the routes that are found by IPX RIP are networks 10,
20, and 30. Here is the output from the 2501C router:

2501C#sh ipx route

[output cut]

5 Total IPX routes. Up to 1 parallel paths and 16 hops

allowed.

No default route known.

C 40 (HDLC), Se0

C 50 (NOVELL-ETHER), Et0

R 10 [13/02] via 40.0000.0c8d.5c9d, 16s, Se0

R 20 [07/01] via 40.0000.0c8d.5c9d, 17s, Se0

Adding Secondary Addresses

hat is the Ethernet frame type we are running on our sample inter-

network? Novell-Ether (802.3). Since we didn't use the encapsulation
command, the default frame type was used.

In this section, I will show you how to configure the other three available

frame types on our Ethernet networks. This is not so you can go and do this
in production--that would be a bad thing. Rather, this is so that when you
see this type of configuration, you know what it is and how to fix it.

To configure multiple frame types on the same LAN network, you can

either use the secondary command or create a subinterface. There is abso-
lutely no functional difference on how the secondary command or how a
subinterface runs on the internetwork. The difference is for administration
purposes only.

Configuring Secondary Addresses

To configure a secondary address on an Ethernet LAN to support multiple
frame types, use the ipx network command with the secondary parameter
at the end of the command.
