To customize hot standby group attributes, use one of the following commands in interface configuration
mode, as needed:
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
Router(config-if)# standby [group-number]
timers hellotime holdtime
Configures the time between hello packets and the hold time before
other routers declare the active router to be down.
Router(config-if)# standby [group-number]
priority priority
Sets the hot standby priority used to choose the active router.
Router(config-if)# standby [group-number]
preempt
Specifies that if the local router has priority over the current active
router, the local router should attempt to take its place as the active
router.
Router(config-if)# standby [group-number]
track type-number [interface-priority].
Configures the interface to track other interfaces, so that if one of the
other interfaces goes down, the hot standby priority for the device is
lowered.
Router(config-if)# standby [group-number]
authentication string
Enables the automatic spanning-tree function on a group of bridged
interfaces.
Command Purpose
Step 1
Router(config)# ipx routing [node]
Enables IPX routing globally.
Step 2
Router(config)# interface type
slot/port.subinterface-number
Specifies the subinterface on which TRISL will be used.
Step 3
Router(config-if)# encapsulation
tr-isl trbrf-vlan vlanid bridge-num
bridge-number
Defines the encapsulation for TRISL.
Step 4
Router(config-if)# ipx encapsulation
encapsulation-type
Specifies the IPX encapsulation.
Step 5
Router(config-if)# ipx network
network number
Specifies the IPX network.
