SDWAN OSPF route filtering

[EminaBrkanic]

Hi all,

is it possible to filter ospf routes. For example, cedge i forming ospf neighbor to other core device that is advertisine some netoworks and default route. I want only to accept def route and send via omp to remote branch.

I know I can create localized policy, route policy but where do I attach that to ospf?

regards

Hello, Emina.

Could you please test it in here ?

Insert local policy name in [Route Policy]

Please remark this as a solution If this is helpful.

Thank you.

This option is to filter router when redistributing from omp into ospf. 

I want to filter ospf routes on cedge routers when receiving from ospf peer.

Hi,

OSPF in service-side is just traditional OSPF. Which means that you can't enforce filtering as you do in BGP/EIGRP (link state VS distance vector logic).

You can do filtering on core switch but this also depends on your area design.

On cedge, there can be option to do it via distribute-list in command. You will still have LSAs in cedge LSDB, but in routing table you will have only 0.0.0.0/0, thus only default route will be redistributed to OMP.
