OSPfv3 IPV4 over local link on freebds
Hi all, I am looking at reducing the number of IPv4s I am using but i'ms truggling to have loopback propagation over local link using OSPv3 on freebsd. Did someone tried it? Can you share your related configuration? when i setup the ip on lo1 and pass as stub in the OSPfV3 IPv4 iinstances, no ipv4 route is exported. any hint is welcome. Benoît
Hoi Benoit, I did not try this on FreeBSD, but I did on Linux: https://ipng.ch/s/articles/2024/06/22/vpp-with-loopback-only-ospfv3-part-2/ and I discussed my travels in Paris at FRNOG'40 in https://video.ipng.ch/w/9A9Zg83PXpunnBvncWYQHL Hope that helps. groet, Pim On 24.01.2025 01:38, benoitc--- via Bird-users wrote:

Thank you, for the linlks :) I was already using your post as a ref but I didn't found the right way to get unnumbered addresses on freebsd. I'm still investigating it My initial expectation however was that it would work the same it does for IPv6 passing the loopback using the local link IP as next hop. But it doesn't seem to it without the trick you use on linux. At least on 1.16.1 . Is there a way to do it wuthout an unnumbered interface ?

Hoi It is not possible because RFC5838 requires an IPv4 address in the IPv6 Link LSA. You cannot do IPv4 unnumbered using link-local because of this requirement. Groet Pim — Pim van Pelt / PBVP1-RIPE https://ipng.ch/
