How to Configure Routing Between VLANS

DETAILED STEPS
Configuring IPX Routing on 802.10 VLANs over ISL
The IPX Encapsulation for 802.10 VLAN feature provides configurable IPX (Novell-FDDI, SAP,
SNAP) encapsulation over 802.10 VLAN on router FDDI interfaces to connect the Catalyst 5000 VLAN
switch. This 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 now configure any one of the three IPX Ethernet encapsulations to be routed
using Secure Data Exchange (SDE) encapsulation across VLAN boundaries. IPX encapsulation options
now supported for VLAN traffic include the following:
• Novell-FDDI (IPX FDDI RAW to 802.10 on FDDI)
• SAP (IEEE 802.2 SAP to 802.10 on FDDI)
Command or Action Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
ip routing
Example:
Router(config)# ip routing
Enables IP routing on the router.
Step 4
interface type slot/port.subinterface-number
Example:
Router(config# interface FastEthernet4/0.1
Specifies the subinterface on which TRISL will be used.
Step 5
encapsulation tr-isl trbrf-vlan vlanid
bridge-num bridge-number
Example:
Router(config-if# encapsulation tr-isl
trbrf-vlan 999 bridge-num 14
Defines the encapsulation for TRISL.
• The DRiP database is automatically enabled when
TRISL encapsulation is configured, and at least one
TrBRF is defined, and the interface is configured for
SRB or for routing with RIF
Step 6
ip address ip-address mask
Example:
Router(config-if# ip address 10.5.5.1
255.255.255.0
Sets a primary IP address for an interface.
• A mask identifies the bits that denote the network
number in an IP address. When you use the mask to
subnet a network, the mask is then referred to as a
subnet mask.
Note TRISL encapsulation must be specified for a
subinterface before an IP address can be assigned to
that subinterface.
