            Bug ID: 264621
           Summary: net/frr ospf6 doesn't transmit on bridge interfaces.
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: dgilbert@eicat.ca

I have FRR OSPF and OSPF6 configured on my lan.  I also have BGP configured,
but not on this host --- so it's just a reference that I "generally" know w=
hat
I'm doing with networks.  On this particular host, I have a number of VMs o=
n a
bridge and one VM will now be configured to receive VPNs... so I want to ex=
tend
OSPF and OSPF6 to the bridge.

Extending OSPF with FRR went as expected.  No problems.

Extending OSPF6 didn't.  No other routers show up on either host or VM.=20
Curiously, while I can IPv6 ping across the interface, no OSPF6 traffic sho=
ws.

Just to short circuit the obvious question, I have

interface bridge1
 ip ospf cost 200
 ip ospf dead-interval 20
 ip ospf hello-interval 5

on the host and

interface vnet0
 ip ospf cost 200
 ip ospf dead-interval 20
 ip ospf hello-interval 5

On the host, I have a host on the ipv6 network with a /64 netmask, and on t=
he
vm I have a host on that same network with a /64 netmask.

host ospf6 clause:
router ospf6
 ospf6 router-id 1.2.3.4
 redistribute kernel
 redistribute connected
 redistribute static
 interface igb0.401 area 0.0.0.0
 interface bridge1 area 2.4.5.6

vm ospf6 clause:

router ospf6
 ospf6 router-id 1.2.3.5
 redistribute kernel
 redistribute connected
 redistribute static
 interface vnet0 area 2.4.5.6

Now... this may be an FRR problem, but I suspect it's a FreeBSD FRR problem=
 as
a tcpdump on the bridge doesn't show ospf6 packets.

The host is 13.0-p11 and the VM is 13.1-RELEASE
