OSPF into EIGRP redistribution

Hello All!

I think I am having a fundamentally wrong understanding of how EIGRP treats routes that have been redistributed from a different routing protocol.

I have 2 routers connected together

R4----R5

I am redistributing OSPF into EIGRP on R4

On R4:

router eigrp 10

redistribute ospf 1 metric 1500 1 255 1 1500

network 129.186.0.0

network 180.1.0.0

no auto-summary

!

On R5 I find my redistributed routes in the EIGRP topology table, however, they show all up like this

P 10.4.4.0/24, 0 successors, FD is Inaccessible

via 129.186.54.2 (2218752/1706752), Serial0/0.45

R5#sh ip eigrp topology 10.4.4.0 255.255.255.0

IP-EIGRP (AS 10): Topology entry for 10.4.4.0/24

State is Passive, Query origin flag is 1, 0 Successor(s), FD is 4294967295

Routing Descriptor Blocks:

129.186.54.2 (Serial0/0.45), from 129.186.54.2, Send flag is 0x0

Composite metric is (2218752/1706752), Route is External

Vector metric:

Minimum bandwidth is 1500 Kbit

Total delay is 20010 microseconds

Reliability is 255/255

Load is 1/255

Minimum MTU is 1500

Hop count is 1

External data:

Originating router is 10.4.4.4

AS number of route is 1

External protocol is OSPF, external metric is 0

Administrator tag is 0 (0x00000000)

What am I doing wrong here?

Thanks

Sascha

I have solved it. I should have thought twice before writing.

The problem was that on R5 I also have an OSPF adjacency. The OSPF routes have a better AD, so that's why my redistribution didn't work.

Yes..

FD inaccessible is an indication that the particular prefix has not been installed in the routing table by EIGRP
