All - a question about Appletalk and AURP:

Here's the scenario:

apple networks 1000, 1002 etc ---r3----aurp-----r4----apple network 4000

r3 can see r4 network 4000 but can't ping (see below)
same with r4 - can see r3 networks in apple routing table, but can't ping.

Any suggestions as to why??

Thanks,

Steve
