5.3 - R2 and route 150.1.2.0 only connected not from R5

Hi

I have question about switching off split horizon on R5 - link connected to FR cloud.

On R2 in topology I see only:

R2#sh ip eigrp 100 topology 150.1.2.0/24
EIGRP-IPv4 Topology Entry for AS(100)/ID(2.2.2.2) for 150.1.2.0/24
  State is Passive, Query origin flag is 1, 1 Successor(s), FD is 128256
  Descriptor Blocks:
  0.0.0.0 (Loopback0), from Connected, Send flag is 0x0
      Composite metric is (128256/0), route is Internal
      Vector metric:
        Minimum bandwidth is 10000000 Kbit
        Total delay is 5000 microseconds
        Reliability is 255/255
        Load is 1/255
        Minimum MTU is 9676
        Hop count is 0
        Originating router is 2.2.2.2

R2#

I can't see prefix 150.1.2.0/24 from R5 via FR link.

We can see, that reported distance is 4294967295. This is caused by poison reverse on R5.

My IOS is version is adventerprisek9-mz.151-3.T2.

Thanks in advance.
