Doubt about OSPF Topology

Dear,

 

I have a question regarding the attached OSPF topology. Here are some details about the topology:

 

* The Neighbor OSPF 1 router can only learn the network route 1
* The Neighbor OSPF 2 router can only learn the network route 2
* The Neighbor OSPF 3 router can only learn the network route 3
* The router RT-001 should establish a neighborhood with all routers

 

How can I configure the RT-001 router to perform this filtering?

I want to control which route will be sent to each client on the router RT-001

If they are separate areas you can inter area filtering but if everything is in the same area you cannot do it all on the RT-001 router because all routers in the same area have the same LSA database.

Re: Doubt about OSPF Topology

Hi

Stupid question here but I see you're taking about different customers for each networks.
Instead of filtering which can be tricky based on what and how everything is configured, why not just splitting each networks into different vrfs on RT-001? (1 vrf per client [network])
Using this, each network will be completely separated.

Thanks
Francesco
