OSPF Redistribution Issue

[Irakli Gvishiani]

Hello, I have implemented OSPF in my network and I have faced with OSPF Redistribution Issue. My topology is next:

Between all 3 devices are running OSPF, but now I need to do some static redistribution and something strange is happening.

For example, if I

add route from 9300 192.168.100.0/24 to FP1140 trough172.31.255.253 

and then do redistribution it not happening... but in ISR 4000 database I see Type 5 LSA:

4431#show ip ospf database
                Type-5 AS External Link States
192.168.100.0 254.254.254.254 11 0x80000001 0x003856 0

But in routing table I don't see this route

4431#show ip route 192.168.100.0 255.255.255.0
% Network not in table

But if I change route, for example to Null 0 or to different direction I will see this route in routing table. 

4431#show ip route ospf
O E1 192.168.100.0/24
[110/520] via 172.31.253.254, 00:00:04, Port-channel19.901

What is the problem? can it be a software bug?

 254.254.254.254 <<- are you sure this is right ?? I dont see this subnet mask before

[Irakli Gvishiani]

Yes, I set Router-ID statically

[MHM Cisco World]

show ip ospf

database external <<- can i see this

[Irakli Gvishiani]

Yes, sure

[MHM Cisco World]

this I think because the link between SW-FW is not known by ISR router, 
and hence when you redistribute the static route it not use by ISR, 
so can you 

A- the interface in SW toward FW 
ip ospf x area x 
B- make the router-id is reachable via ISR (using LO as Router-ID)

[Irakli Gvishiani]

1 - ISP Router knows IP address of Link between SW-FW, but through EIGRP

2 - But Router-ID is not routable and, therefore, is not included in the routing table and I can't change it

[MHM Cisco World]

OK, then try redistribute the static route via EIGRP not via OSPF. are this OK for you ?

[MHM Cisco World]

I will run lab see how we can solve this issue. 

[Irakli Gvishiani]

Yes, as I see there is no problem with EIGRP.

Route is added into routing table and distributed through VPN tunnels as need. 

[MHM Cisco World]

Yes because the EIGRP know the next-hop of static route and hence it success to add static route in ISR router.

[Irakli Gvishiani]

Ohhh.. I was

filtering this 192.168.100.0/24 route through distribute-list =\

Thank you for your assist @MHM Cisco World!
