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.
