The way I have always done it is
access-list 901 deny any any all any sap
access-list 901 deny any any all any rip
access-list 901 deny any any all any 457
access-list 901 permit any any all any all
Little different

Subject: ISDN - IPX
Hey guys, I've been testing ISDN with IP and I'm just about to configure IPX
maps too using Legady DDR. I would like to know if the following acl will
prevent the unwanted IPX traffic to bring up the link (saps, rip,
serialization)
access-list 900 deny sap any all any sap
access-list 900 deny rip any all any rip
access-list 900 deny any any all any 457
access-list 900 permit any any all any all
Is this acl correct, plus should I block/unblock something else?
TIA!!
cheers,
hockito

But it will not provide the backup function in the event LanA is not
reachable via IA(R-A).
I will give a try on the method which I post earliest and check does it
function as a backup
(alternative path).

Another solution i found working on this was to use
distribute list on rtrB,
I denied lanA network using input distribute list on
rtrB
It prefered the IA network. Not that it is a clean
solution but serves the topology given below and meets
the purpose.
thanks
