AppleTalk: Users Cannot Access Zones or Services (continued)
Possible Problems
Solution
Duplicate network
numbers or overlapping
cable-range
In AppleTalk, network numbers must be unique within an
internetwork. If duplicate network numbers exist, packets
might not be routed to their intended destinations.
If AppleTalk services do not appear in the Chooser for
particular networks, those networks probably have
duplicate network numbers.
1.
Change the network number or cable-range of the
suspect network to a unique value using the
appletalk cable-range
interface configuration
command.
2.
Use the
show appletalk route privileged exec
command to view the routing table. If the network
number or cable-range continues to appear in routing
tables, you have found the duplicate (because the
other network using that number will continue to send
routing updates).
If the network number or cable-range disappears from the
internetwork after 40 seconds, you have not found the
duplicate. Change the network number or cable-range
specification back to its previous value and try again to
isolate the duplicate network number.
If you changed the network number or cable-range on
the interface, remember to reenter the zone name and
any other interface configurations for AppleTalk on
that interface.
