Creating/Deleting Static Routes; Configuring Type-20 Packet Forwarding - Alcatel-Lucent OmniSwitch 6850-48 Network Configuration Manual

IPX Routing
The network node is only required if the default network is directly connected to the switch. For example,
to create a default route to network 222 (which is directly attached to the switch) you would enter:
-> ipx default-route 222 00:20:da:99:88:77
Use the no ipx default-route command to delete a default route. For example, to delete a default route by
using the 222 network as a first hop you would enter:
-> no ipx default-route 222
Use the show ipx default-route

Creating/Deleting Static Routes

A static route enables you to send traffic to a switch other than those learned through routing protocols.
Static routes are user-defined and carry a higher priority than routes created by dynamic routing protocols.
That is, if two routes have the same metric value, the static route has the higher priority. Static routes
allow you to define or customize an explicit path to an IP network segment, which is then added to the IP
forwarding table. Static routes can be created between VLANs to enable devices on these VLANs to
communicate.
Use the ipx route command to configure a static route for the switch. Enter the IPX network number of
the route's final destination, then enter the IPX network and node numbers used to reach the first hop of
the route. You can also enter the optional parameters of hop count (number of hops to the destination
network) and delay. The delay is the time, in ticks, to reach the route's destination. One tick is equivalent
to 1/18 of a second (approximately 55ms).
For example, to create a static route to network 222 with a first hop network of 0000590C node
00:20:da:99:88:77, you would enter:
-> ipx route 222 590C 00:20:da:99:88:77
Static routes do not age out of the routing tables; however, they can be deleted. Use the no ipx route
command to delete a static route. To delete a static route, you only need to enter the network number of
the destination node. For example, to delete a static route to network 222 you would enter:
-> no ipx route 222
Use the show ipx route

Configuring Type-20 Packet Forwarding

Type 20 is an IPX packet type that refers to any propagated packet. Novell has defined the use of these
packets to support certain protocol implementations, such as NetBIOS. Because these packets are broad-
cast and propagated across networks, the addresses of those networks (up to eight) are stored in the
packet's data area. If Type 20 packet forwarding is enabled, the switch receives and propagates Type 20
packets through all its interfaces. If Type 20 packet forwarding is disabled, the switch discards, rather than
propagates, any Type 20 packet it receives. Type 20 packet forwarding is disabled by default. This is
because these packets can cause problems in highly redundant IPX networks by creating what appears to
be a broadcast storm. This problem is aggravated whenever misconfigured PCs are added to a network.
Use the ipx type-20-propagation
For example:
