Thanks Ondrej, so far I faced it with using direct protocol interface advertisement. I might try by creating loopbacks with the same /32 address I want to be propagated. In my current setup it should work straight away, but in other situations the creation of loopbacks with the sole purpose of advertising a /32 p2p endpoint might just increase configuration complexity (one for all, DR/BDR election process). Looking forward a configurable option in future versions, thanks a lot daniele On 02/06/15 11:43, Ondrej Zajicek wrote:

Hi all, Is it normal that routes flagged as H, ie. /32 routes in p2p links in linux routing table, are not learnt and distributed by ospf? In my ospf area I need all the routers to know about the different p2p endpoint addresses which are not distributed by ospf in bird4. The only networks that are distributed are non-p2p subnets. Currently the only way to make this happen is to manually set some /32 static routes.. not really flexible. Hi
Non-stub ptp addresses are not propagated by design based on assumption that in many cases you either don't want them to be propagated or are propagated anyways as 'loopback' /32 addresses. And it is generally easier to add stub address when necessary than remove them when unwanted.
But i admit that this is counterintuitive and sometimes impractical and we should have some configurable option to handle it, with default to distribute them.
