The IPX router ignores any dynamic updates or backup routes on the 
network when a static route is configured for a specific network. Static 
routes are recommended only where the network topology remains 
constant.

Define a static route using:

ADD !<port> -IPX ROUte {&<remote network> | Default} [<network>] 

<media address> <hops> [Override] [hdrfmt]

You can configure a static default route, which is subsequently added 
to the routing table and propagated by NRIP or NLSP. Once a default 
route is specified, packets destined to unknown networks (networks 
not explicitly known or listed in the routing table) are routed to the 
default router for subsequent routing. You can configure only one 
default route per port.

Use this procedure to configure a default route so that unknown 
destination packets can be properly forwarded. Define a static default 
route using:

ADD !<port> -IPX ROUte Default <media address> <hops>

If a destination network is reachable with both a static route and a 
learned route, the router uses the static route unless you specify the 
optional Override value in the ADD ROUte command. In that case, if a 
learned route is available, regardless of precedence, it overrides the static 
route. You should specify Override for a path you want to use for route 
redundancy. The Override value is entered at the end of the command. 

If your primary line fails, you can use a back-up line to route traffic by 
configuring route redundancy.To configure a back-up line for route 
redundancy, configure the line according to Chapter 7.

If you use a static route on the back-up line, but use a dynamic routing 
protocol like NLSP on the primary line, use the Override option as 
described in “Override Option” on page 110.

If you are using static routes for both lines, set the hops for the back-up 
line to a higher number using the syntax in “Configuring Static Routes” 
on page 109.
