Configuring Routing Between VLANs

How to Configure Routing Between VLANS

Configuring IPX Routing over TRISL

The IPX Routing over ISL VLANs feature extends Novell NetWare routing capabilities to include

support for routing all standard IPX encapsulations for Ethernet frame types in VLAN configurations.

Users with Novell NetWare environments can configure either SAP or SNAP encapsulations to be routed

using the TRISL encapsulation across VLAN boundaries. The SAP (Novell Ethernet_802.2) IPX

encapsulation is supported for VLAN traffic.

NetWare users can now configure consolidated VLAN routing over a single VLAN trunking interface.

With configurable Ethernet encapsulation protocols, users have the flexibility of using VLANs

regardless of their NetWare Ethernet encapsulation. Configuring Novell IPX encapsulations on a

per-VLAN basis facilitates migration between versions of Netware. NetWare traffic can now be routed

across VLAN boundaries with standard encapsulation options (sap and snap) previously unavailable.

Encapsulation types and corresponding framing types are described in the “Configuring Novell IPX”

chapter of the Cisco IOS AppleTalk and Novell IPX Configuration Guide.

Note Only one type of IPX encapsulation can be configured per VLAN (subinterface). The IPX encapsulation

used must be the same within any particular subnet: A single encapsulation must be used by all NetWare

systems that belong to the same LANs.

To configure Cisco IOS software to exchange different IPX framing protocols on a router with connected

VLANs, perform the steps in the following task in the order in which they are appear.

SUMMARY STEPS

1. enable

2. configure terminal

3. ipx routing [node]

4. interface type slot/port.subinterface-number

6. ipx network network encapsulation encapsulation-type

Step 4

interface fddi slot/port.subinterface-number

Example:

Router(config)# interface 2/0.1

Specifies the subinterface on which SDE will be used.

Step 5

Example:

Router(config-if)# encapsulation isl 20

Defines the encapsulation format and specifies the VLAN

identifier.

Step 6
