EIGRP issue using VRF on 3750

Question:

I am in the WS-C3750X-24P-S  Lab playing with VRF, got it to work when the switchport itself is a no switchport with IP address, however if I stick the Wan connecting interface into a vlan EIGRP wont create a Neighborship though I can ping it under that VRF.

interface FastEthernet1/0/1
description WAN interconnection
switchport access vlan 5


router eigrp 90
address-family ipv4 vrf NHSS
  network 10.202.128.0 0.0.31.255
  passive-interface default
  no passive-interface FastEthernet1/0/1
  autonomous-system 90
exit-address-family

interface Vlan5
ip vrf forwarding NHSS
ip address 10.202.128.200 255.255.255.0

switch-x#ping vrf NHSS 10.202.128.12

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.202.128.12, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/8 ms
switch-x#


switch-x#sh ip eigrp vrf NHSS ne
EIGRP-IPv4 Neighbors for AS(90) VRF(NHSS)
switch-x#

So does anyone know why I cant neighbour 10.202.128.12 now that f1/0/1 is a switchport and in a vlan?


Config:-

Any ideas?

Many thanks in advance,

Answer:

This starts to look like an IOS bug. Can you perhaps try to totally remove the entire EIGRP configuration and configure it completely anew? Avoid configuring the passive interfaces at this point. In addition, can you assign the "global" EIGRP process a different AS number than the ASN 90 for the NHSS VRF EIGRP?

I assume that interface Vlan5 reports as "up, line protocol up" - a silly question considering the fact that you can ping the other party but nevertheless - let's check it. WS-C3750V2-24PS-S
