I noticed the same issues.
After upgrading one of my BGP routers I got blackholes in my IPv6 OSPF
core.
I'm using 0.99.24.1 in my core network and the router I upgraded was
upgraded to version 1.1.
After downgrading the router again everything was fixed.

I have a custom version that I built using the 418805 revision of the port
and the quagga-1.0.20161017 revision of the tarball. The current version
of the port won't patch the older tarball.

That said, 1.0.20161017 works for ipv6 (although ospf6d has a tendency to
crash every so often) and 1.1.0 is broken.

At this moment version 0.99.24.1 is stable with both OSPFv2 and OSPFv3.
I have some issues with BGP though, see my mails with subject "Serious
BGP issue"

Can you clarify on the “broken” in 1.1.0?

- FreeBSD Version?
- Broken = no neighbors formed? No routes in routing table?

Thanks,
Martin

FreeBSD 11.0 but it's not related to FreeBSD because users have reported
the same issue on Linux.

Neighbors are formed but no routes in routing table.

Between 1.0.20160315 and 1.1.0 the following commit have been done:
ospf6d: fix off-by-one on display of spf reasons
ospf6d: don't access nexthops out of bounds
ospf6d: Fix double increment of Sequence Number
ospf6d: Fix loss of hello's on interface
ospf6d: Adding the initialization check in ospfv3_clean()
ospf6d: Fixing a couple of issues with ospf6_route_remo...
ospf6d: LA (local-address) bit related inter-op fix.
ospf6d: We should accept long form of "no redistribute"
ospf6d: Add the missing ospf6 running check in show...
ospf6d: Support for 'clear ipv6 ospf6 interface [ifname]
opsf6d: Update router-LSA when nbr's interface-ID changes
ospf6d, ripd, vtysh: Fix "no set metric" for ospf6...
ospf6d: implement admin distance

One of this commit break ospf6d.

Thanks

I’ve reproduced the issue and created a topology test for it.

Thanks to Jan Hugo Prins for his time to help me debug this. Don’t know
why this didn’t trigger an error in my RFC compliance tests)

Test is requires a Ubuntu 16.04 with Mininet installed

Python script for the test and documentation is in the git at
https://git.netdef.org/scm/netdef/topotests.git

I’m going to add this test to my CI system AFTER the code is fixed
(otherwise every patch submission will be flagged as bad)

Regards,
Martin Winter


PS: I have not spent time in any bisect or any search for the bad
commit. I hope someone else here takes over…

PSS: I’m working on topology tests for some time and I’m planning to add
more to the automated tests. Working on some BGP tests as well and
want to add several tests with route-map and redistribution etc to it.
Suggestions welcome…
