THis came up a while back. It can be fixed without breaking the usual restrictions by adding two lines of ip nat config as follows:
   
  interface FastEthernet0/0
 ip address 1.1.2.1 255.255.255.0 secondary
 ip address 1.1.1.1 255.255.255.0
 ip nat outside
  !
  ip nat inside source static 1.1.1.1 1.1.2.3

  Dear Group Study gurus:

I have a question about secondary address issue in eigrp.
Is it possible to forming adjacency from different primary network addresses
on two routers?
This is an imaginary scenario.
Say two routers -- R1 and R2

R1(e0/0) -----------------(e0/0)R2

R1
Interface e0/0
Ip address 1.1.1.1 255.255.255.0
Ip address 1.1.2.1 255.255.255.0 secondary
Router eigrp 1
Network 1.0.0.0

R2
Interface e0/0
Ip address 1.1.2.2 255.255.255.0
Router eigrp 1
Network 1.0.0.0

In rip world we have an option called "no validate-update-source" to conquer
this restriction.
But after searching the CCO I could not find the equivalent as above in
eigrp world.

Can we still have the adjacency forming up without change the primary or
secondary address?

Thanks

Lin
