The frame switch configuration appears to be a full mesh and more. While you
are only statically creating a map from R2-R1 and R3-R1 the wonderful
frame-relay inverse arp facility is also creating a map between R2-R3
without your help.
If you do a show frame map, I believe you will see a dynamic mapping between
R2-R3 in addition to the static ones you created.
This additional mapping is why you are observing the EIGRP on different
network errors. Routers R2 and R3 are on different subnets so they are
wondering why they are seeing hellos that aren't on their subnet....
This error is a result of the they dynamic frame map.
Disable auto mapping with no frame inverse arp under the physical interface,
reload, and you should be good to go.

Subject: EIGRP: Neighbor not on common subnet
I am yet to figure out why I am getting this message on a very simple
frame-relay+Eigrp setting.
Here is the diagram and router configs: http://24.234.55.18/out/eigrp.jpg
The frame switch config is:
!
interface Serial1
no ip address
encapsulation frame-relay
clockrate 56000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 912 interface Serial2 921
frame-relay route 913 interface Serial3 931
frame-relay route 914 interface Serial4 941
frame-relay route 915 interface Serial5 951
frame-relay route 916 interface Serial6 961
frame-relay route 917 interface Serial7 971
!
interface Serial2
no ip address
encapsulation frame-relay
clockrate 56000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 921 interface Serial1 912
frame-relay route 923 interface Serial3 932
frame-relay route 924 interface Serial4 942
frame-relay route 925 interface Serial5 952
frame-relay route 926 interface Serial6 962
frame-relay route 927 interface Serial7 972
!
interface Serial3
no ip address
encapsulation frame-relay
clockrate 56000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 931 interface Serial1 913
frame-relay route 932 interface Serial2 923
frame-relay route 934 interface Serial4 943
frame-relay route 935 interface Serial5 953
frame-relay route 936 interface Serial6 963
frame-relay route 937 interface Serial7 973

on R2 I get the message:
01:38:16: IP-EIGRP: Neighbor 10.155.1.6 not on common subnet for Serial0
on r3 I get the message:
01:38:53: IP-EIGRP: Neighbor 10.155.1.2 not on common subnet for Serial0
I've checked CCO. although there is an explanation for it at
http://www.cisco.com/warp/public/103/15.html
but I can not relate.
Can some one shed a light Please?
TIA
Akim
