ospf6d cannot generate route. about ospf-mdr

Yes, it can.

Would you care to provide any context or details here? Are you asking for configuration assistance, or do you think you found some sort of reproducible bug?

Is this related to your closed CORE bug, and have you followed the basic steps of downloading, building, and installing this software on your host OS so that it will be available to CORE? CORE includes service configuration for ospf6d/zebra, but does not include the software itself.

My system is ubuntu22, the latest version of core installed. No error is reported when core runs. ospfv3 hello packets sent between containers are normal, but ipv6 routes cannot be generated. We had this problem before, but with ubuntu20, we uninstall it and installed quagga directly, but quagga is difficult to install on ubuntu22.

ospfv2 is running properly

This OSPF-MDR version includes extensions to ospv6d to better support MANET wireless networks. If you're just using this in a wired CORE network, default Quagga ospf6d should work fine. I am not sure what issues you are having installing that in Ubuntu 22 (default CORE-compatible Quagga build process is documented here), but it seems odd that switching to default Quagga would fix your problem in the first place.

I am not personally up to date on the latest CORE releases, nor am I personally aware of any differences between this codebase (based on Quagga 0.99, I believe) and where default Quagga is now (I moved this code to github, but I am not the author/developer). It could be that newer CORE has switched to some newer Quagga configuration that is incompatible with this version, but that's a guess, having not even tried to reproduce this. Hopefully one of the developers (of ospf-mdr or CORE) can comment further.

Just to add to what @weston-nrl said, if you just need basic routing, then you don't need the quagga in this repo. Quagga technically is no longer developed, and that is why it is not available in Ubuntu 22.04. It's replacement is frr (sudo apt install frr). FRR should work with CORE.

CORE currently pulls OSPF-MDR in as part of its build. FRR would have to be installed separately and OSPF-MDR removed.

There is some basic support for FRR in CORE with a set of FRR services that I prototyped and were merged, but not sure if anyone is actively using FRR in CORE. Either FRR or OSPF-MDR can be installed, but not both concurrently due to the collision of libraries and binaries.

When installing CORE (clean install), you can skip ODPF-MDR installation with inv install --no-ospf
