Router not advertising a redistributed route

Syfusion

Hey guys, studying for ICND 200-105 test but I think I may have veered off into CCNP territory with this question.

I have 4 routers arranged like a diamond with the 2 middle routers sharing a connection. The two middle routers have ospf and rip redistributed with the top router being rip only and the bottom router ospf only. On the top router I have 2 servers with the bottom router having a host computer. My problem is that the top router does not have an entry for the network that the host computer resides on even though my two middle routers know about it.

Do I need to use static routes pointing back to the bottom router or am i missing something?

Mr.Network

can you post the "sh ip route" of the routers.

Redistribution is in the exams outline but don't know how much the want you to know. It is CCNP. Need the IP address of the servers and and the route statements for the two redistribution routers.

Also do you have the subnet command enabled.

The general goal at first was to make the comp take the right side to get to the 192 server and take the left path to get to the 172 server but I don't think packet tracer is advanced enough for policy routing.

The routers just have basic redistribute statements, nothing specific.

It's best to put a link to the PT file or post your config for all the routers.

Not enough information provided. We will need the full running config of all routers involved. As well as information on the top and bottom subnets. Also, as it appears you are running OSPF and RIP, please post the "sh ip OSPF database" output from all routers running OSPF and the "sh ip RIP database" output from all routers running RIP. And as suggested posting the .PKT file for the lab will possibly help, if you are using packet tracer.
