Configure AppleTalk Routing over IEEE 802.10

AppleTalk can be routed over VLAN subinterfaces by using the ISL or IEEE802.10 VLAN encapsulationprotocols. The AppleTalk Routing over IEEE 802.10 Virtual LANs feature provides full-feature Cisco IOS software AppleTalk support on a per-VLAN basis, allowing standard AppleTalk capabilities to be configured on VLANs.

AppleTalk users can now configure consolidated routing over a single trunking interface. Prior to introduction of this feature, AppleTalk could be routed only on the main interface on a LAN port. If AppleTalk routing was disabled on the main interface or if the main interface was shut down, the entire physical interface would stop routing any AppleTalk packets. With this feature enabled, AppleTalk routing on subinterfaces will be unaffected by changes in the main interface with the main interface in the "no-shut" state.

To route AppleTalk over IEEE 802.10 between VLANs, create the environment in which it will be used by customizing the subinterface by performing these tasks in the order in which they appear:

• Enabling AppleTalk Routing

• Configuring AppleTalk on the Subinterface

• Defining the VLAN Encapsulation Format

Enabling AppleTalk Routing

To enableAppleTalk routing on IEEE 802.10 interfaces, use the following command in global configuration mode:

Command	Purpose
appletalk routing [eigrp router-number]	Enables AppleTalk routing globally.

Configuring AppleTalk on the Subinterface

After you enable AppleTalk globally and define theencapsulation format, youneed to enable it on the subinterface by specifying the cable range and naming the AppleTalk zone for each interface. To enable the AppleTalk protocol on the subinterface, use the following commands in interface configuration mode:

Command	Purpose
appletalk cable-range cable-range [network.node]	Assigns the AppleTalk cable range and zone for the subinterface.
appletalk zone zone-name	Assigns the AppleTalk zone for the subinterface.

Defining the VLAN Encapsulation Format

To define the VLAN encapsulation format as either ISL or 802.10, use the following commands in interface configuration mode:

Step	Command	Purpose
1	interface type slot/port.subinterface-number	Specifies the subinterface the VLAN will use.
2	encapsulation sde said	Defines the encapsulation format as IEEE 802.10 (sde) and specifies the identifier or security association identifier, respectively.
