Ok, I just checked this in the lab:

You definitly need the "autonomous-system <n>" in the ipv4-vrf AF config
(as described in the docs), without it the EIGRP vrf process is not
fully initialized:


r1#sh run | b router eigrp 200
router eigrp 200
 auto-summary
 !
 address-family ipv4 vrf green
 network 10.0.1.0 0.0.0.255
 auto-summary
 exit-address-family
!

r1#sh ip protocols vrf green
Routing Protocol is "eigrp 0"      <<<<<<<<<< Zero shown here
...
r1#sh ip eigrp vrf green interfaces  <<< no interface
r1#

r1#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
r1(config)#router eigrp 200
r1(config-router)#address-fam ipv4 vrf green
r1(config-router-af)#autonomous-system 200
r1(config-router-af)#^Z
r1#
r1#sh ip eigrp vrf green interfaces 
IP-EIGRP interfaces for process 200

                        Xmit Queue   Mean   Pacing Time   Multicast
Pending
Interface        Peers  Un/Reliable  SRTT   Un/Reliable   Flow Timer
Routes
Et0/0.20           0        0/0         0       0/10           0
0
r1#sh ip protocols vrf green        
Routing Protocol is "eigrp 200"
...

voila.

You can either use your setup (with the additional command), or use the
one proposed by me with a single process.
