Configuring Routing Between VLANs

How to Configure Routing Between VLANS

• SNAP (IEEE 802.2 SNAP to 802.10 on FDDI)

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

FDDI interface. Not all IPX encapsulations are currently supported for SDE VLAN. The IPX interior

encapsulation support can be achieved by messaging the IPX header before encapsulating in the SDE

format. Fast switching will also support all IPX interior encapsulations on non-MCI platforms (for

example non-AGS+ and non-7000). 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 (arpa, 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 VLAN.

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

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