Re: Question about IPX SAPs

Curtis: SAPs will not be broadcast out the interface they are learned
on. As an example, configure static SAPs and, with default routes,
point the static SAP network to different interfaces on the router. You
will see the static SAPs advertised out the IPX enabled interfaces
except the interface in the default route.

Example: you have two Ethernet interfaces e0 with IPX network 10 and e1
with IPX network 20. Define two static SAPs:
        ipx sap 04 Zero aaa.0.0.1 451 2
        ipx sap 04 One bbb.0.0.1 451 2
Define two default routes, ipx route aaa 10.0000.1234.5678
                           ipx route bbb 20.0000.5678.9abc
You will see Zero advertised on e1 and One advertised on e 0.

HTH, Fred.
