Tim,
My "sh ip arp" was from R3 where yours was from R6, that's why your output references BVI1 instead of the interface. Issue the command from your other routers to see of the ARP process is completing successfully between edge routers.
IP ARP traffic will pass through IP access-list security, which may help identify any security misconfigurations. It's also possible that one router can correctly resolve the other but not vice versa, which could be due to an 802.1Q native VLAN mismatch (among other things). The results of the 'sh ip arp' might give you a better idea of where to focus your troubleshooting though.

Hey Tom,
I'm starting to get the feeling that the problem is some stupid little thing
I'll be very embarrassed by once this is figured out. But, so far, I can't
figure out what's causing this problem. Here's some output from R6:
[snip]
Rack1R6#sh ip arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 136.7.136.6 - 0050.d15f.7420 ARPA BVI1
Internet 136.7.136.3 0 0002.fd3d.e081 ARPA BVI1
Internet 136.7.136.1 0 0002.b988.bde0 ARPA BVI1
Internet 204.12.7.6 - 0050.d15f.7420 ARPA
FastEthernet1/0/0.6
[snip]
Some things I noticed while comparing outputs. In your show ip arp, the
interface referenced was fa0/0 while my output referenced BVI 1. Do you
know why that is? Does it matter in this scenario?
