Cisco Systems BC-145 manual Configuring IPX Routing over TRISL, BC-150, Command, Purpose

Configuring Token Ring Inter-Switch Link

TRISL Configuration Task List

To customize hot standby group attributes, use one of the following commands in interface configuration mode, as needed:

Command	Purpose
Router(config-if)# standby [group-number]	Configures the time between hello packets and the hold time before
timers hellotime holdtime	other routers declare the active router to be down.
Router(config-if)# standby [group-number]	Sets the hot standby priority used to choose the active router.
priority priority
Router(config-if)# standby [group-number]	Specifies that if the local router has priority over the current active
preempt	router, the local router should attempt to take its place as the active
	router.
Router(config-if)# standby [group-number]	Configures the interface to track other interfaces, so that if one of the
track type-number [interface-priority].	other interfaces goes down, the hot standby priority for the device is
	lowered.
Router(config-if)# standby [group-number]	Enables the automatic spanning-tree function on a group of bridged
authentication string	interfaces.

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 Token Ring 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.

Netware users can now configure consolidated VLAN routing over a single VLAN trunking interface. With configurable Token Ring encapsulation protocols on a per VLAN basis, users have the flexibility of using VLANs regardless of their NetWare Token Ring encapsulation. 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 LAN.

To configure Cisco IOS software to route IPX on a router with connected VLANs, use the following commands beginning in global configuration mode:

		Command		Purpose
Step 1
		Router(config)# ipx routing [node]		Enables IPX routing globally.
Step 2
		Router(config)# interface type		Specifies the subinterface on which TRISL will be used.
		slot/port.subinterface-number
Step 3
		Router(config-if)# encapsulation		Defines the encapsulation for TRISL.
		tr-isl trbrf-vlan vlanid bridge-num
		bridge-number
Step 4
		Router(config-if)# ipx encapsulation		Specifies the IPX encapsulation.
		encapsulation-type
Step 5
		Router(config-if)# ipx network		Specifies the IPX network.
		network number
