Passive interface and Static route redistribution are not working

[turbo_engine26]

Hello,

Please find attached scenario with configuration files

This topology is intended for Router Redistribution scenario.

Issue #1:

Robinson is a router that runs both OSPF and RIP.

RIP is running on Robinson's f0/1 interface and OSPF is running on Robinson's f0/0 interface. Both interfaces share the same major network 192.168.3.0/24. Because RIP will run on this major network, f0/0 interface should be passive under RIP since f0/0 listens for OSPF packets.

However, Podres's route table shows that 192.168.3.32/27 is a RIP entry which is not good because it should appear as a RIP entry only after redistributing it to the RIP domain. For OSPF, there was no need to configure passive interface on f0/1 because i specified the exact network to run under OSPF.

Issue #2:

Because RIP is classful and doesn't support summarization, there was no way to summarize redistributed routes from OSPF domain to RIP domain. So, i created a static route to 192.168.3.64/27 and 96/27 in Robinson then i redistributed it to RIP. When i went to see Podres's route table, it didn't show any summarized entry. Summarization from RIP to OSPF working good, that's why i love classless protocols.

Appreciate your response.

Regards,

You can use RIP summarization under the interface config mode example:

 (config-if)# ip summary-address rip 10.2.0.0 255.255.0.0

Make sure under rip config you those commands

Router rip

Version 2

No auto-summary

Well, Thx for the solution but this is not a correct one.

What i want to do here is, to summarize the redistributed routes came from OSPF and entering RIP domain. Your solution is to summarize the internal RIP network to the external world which is totally different thing. Unfortunately, only Cisco EIGRP,OSPFv2 and IS-IS support summarization of redistributed routes. One way to solve this is to create a static route in Robinson (the middle router) to point to the summary address of the destination subnets. For example, 192.168.3.64/27 and 96/27 can be summarized as 192.168.3.0/25. So, ip route 192.168.3.0 255.255.255.128 192.168.3.33 is created. The next step is redistribute that static route into RIP domain using redistribute static command under RIP process but it is not working .. that's why i need help here.

Thx a lot for your effort anyways.

This to summarize rip routes to rip domain on certain interface for any route in rip routing table regardless it is redistributed or not you can use distribute-list out with this summarization to filter other routes and send the summary only to the rip domain

Please explain practically in my topology layout.
