Configuring IPX forwarding feature
IPX RIP and SAP periodically broadcast updating packets. With the triggered updating feature enabled,
updating packets will be sent only upon route or service information changes, and flooding of
broadcasts can be avoided.
Split horizon can avoid routing loops—routing information received from an interface is not permitted to
be sent from the interface. In some cases, split horizon must be prohibited to ensure correct routing
information transmission. In addition, split horizon prohibition does not take effect on point-to-point links.
The type 20 IPX packet is used in NetBIOS. You can either prohibit or permit the forwarding of type 20
broadcast packets based on the actual requirements.
To configure IPX triggered updating feature:
Step Command Remark
32. Enter system view. system-view N/A
33. Enter interface view.
interface interface-type
interface-number
N/A
34. Enable the IPX triggered
update feature.
ipx update-change-only Disabled by default.
35. Enable the IPX split horizon
feature.
ipx split-horizon
Optional.
Enabled by default.
36. Configure the encapsulation
format of IPX frames.
ipx encapsulation [ dot2 | dot3 |
ethernet-2 | snap ]
Optional.
The default is Ethernet_802.3
(dot3).
37. Configure an IPX forwarding
delay.
ipx tick ticks
Optional.
By default, 1 tick for Ethernet
interfaces and VLAN interfaces, 30
ticks for asynchronous serial ports, 6
ticks for synchronous ports, with
each tick roughly being 1/18
second.
38. Enable the forwarding of
type 20 packets.
ipx netbios-propagation Disabled by default.
