Bob,

I will go with the following: If you look at it, your first command is
redundant.

access-list 900 deny rip any rip any rip
access-list 900 deny sap any sap any sap
access-list 900 deny any any 457
access-list 900 permit any

Subject: IPX access-list to block rip and sap

When creating an access-list that blocks all ipx rip,sap and serialisation
packets but allow ipx pings and all other traffic I do

access-list 900 permit rip any cping any cping
access-list 900 deny rip any rip any all
access-list 900 deny sap any sap any all
access-list 900 deny any any 457
access-list 900 permit any

In a bootcamp lab (5) their answer is

access-list 901 deny any any all any rip
access-list 901 deny any any all any sap
access-list 901 deny any any all any 457
access-list 901 permit any any all any all

I know my list blocks rip and sap but as I have very little real life ipx
experience so can anyone explain the difference or which more correct?

Thanks

Bob
