appletalk filter question

 Ethernet ( 666-666 666-zone) R1 Frame relay R2 Ethernet (11-11
11-zone)

AT routing is working fine at this point, I see all other cable ranges and
zones I should

make it so clients on R1 cannot see zones directly attached to R2
The frame cloud is using AT EIGRP routing. RTMP is disabled on the serial
interfaces.

I think there are 2 ways to do this

1: create a getzonelist filter that filters the 11-zone, allows all other
zones and access. apply it to R1's Ethernet segment. Like this:

AppleTalk access list 600:
  deny zone 11-zone
  permit additional-zones
  permit other-access

2: create a routing filter and issue a distribute-in command on R1's serial
interface
Like this:

AppleTalk access list 601:
  permit additional-zones
  deny cable-range 11-11
  permit other-access

I think #2 could be used if the question were worded a little different.
Example: to deny access from any segments on R1 to R2

here is the problem: when using #2 I issue a "sh apple zone" I see the
11-zone listed with no cable segment. Is this normal?

I though that if the router received a zone with no cable segment it
wouldn't put it in the table. If I didn't have the
getzonelist filter on E0, wouldn't clients get the 11-zone in the chooser
but not be able to get there?

the docs say the order of the access lists don't make any difference (unlike
other access lists)

am I on the right track here ?
