OSPFv3 not finding neighbors

Hi,

I am observing the following situation on multiple routers (various platforms - powerpc, x86, so far haven't seen it on mipsle/mipsbe; also different ROS versions are affected, I have observed this on ROS 3.20 and 3.22):

I am trying to set up an IPv6 OSPFv3 routing on ROS. The boxes have both routing-test and mpls-test packages installed (those are required for OSPFv3 to work).

The configuration of one box follows:

[admin@xxx] /routing ospf-v3> export
# mar/30/2009 11:46:50 by RouterOS 3.22
# software id = K1GZ-RVT
#
/routing ospf-v3 instance
set default comment="" disabled=no distribute-default=never metric-bgp=20 \
    metric-connected=20 metric-default=1 metric-other-ospf=20 metric-rip=20 \
    metric-static=20 name=default redistribute-bgp=as-type-2 \
    redistribute-connected=as-type-1 redistribute-other-ospf=as-type-1 \
    redistribute-rip=as-type-2 redistribute-static=as-type-1 router-id=\
    10.152.0.1
/routing ospf-v3 area
set backbone area-id=0.0.0.0 disabled=no instance=default name=backbone type=\
    default
/routing ospf-v3 interface
add area=backbone cost=10 dead-interval=40s disabled=no hello-interval=10s \
    instance-id=0 interface=all network-type=default passive=no priority=1 \
    retransmit-interval=5s transmit-delay=1s

The configuration of another box follows:

[admin@yyy] /routing ospf-v3> export
# mar/30/2009 11:47:39 by RouterOS 3.22
# software id = 9ZF1-PTT
#
/routing ospf-v3 instance
set default comment="" disabled=no distribute-default=never metric-bgp=20 metric-connected=20 metric-default=1 \
    metric-other-ospf=20 metric-rip=20 metric-static=20 name=default redistribute-bgp=no redistribute-connected=\
    as-type-1 redistribute-other-ospf=no redistribute-rip=no redistribute-static=as-type-1 router-id=10.128.9.1
/routing ospf-v3 area
set backbone area-id=0.0.0.0 disabled=no instance=default name=backbone type=default
/routing ospf-v3 area range
add advertise=yes area=backbone cost=calculated disabled=no range=::/0
/routing ospf-v3 interface
add area=backbone cost=10 dead-interval=40s disabled=no hello-interval=10s instance-id=0 interface=bridge1 \
    network-type=broadcast passive=no priority=1 retransmit-interval=5s transmit-delay=1s
add area=backbone cost=10 dead-interval=40s disabled=no hello-interval=10s instance-id=0 interface=wlan1 \
    network-type=broadcast passive=no priority=1 retransmit-interval=5s transmit-delay=1s

On both boxes when I run

/routing ospf-v3 neighbor print

the output is just a single empty line. No other output is present. Also OSPFv3 does not load and distribute routes thus making the whole network configuration unusable. E.g.:

[admin@yyy] /routing ospf-v3> neighbor print 

[admin@yyy] /routing ospf-v3>

Any ideas what am I doing wrong?

Thanks,
Radek

Do you have queues set up on the same interface where ospf-v3 is running?

Uhm. Yes.
Just tried removing the queue on one of the boxes, cloaked as "yyy" in the first post, and the box does find neighbors now.
Unfortunately the other box, cloaked as "xxx", has to have queues set up and enabled. Is there a way how to make OSPFv3 work with queues?

Thanks again.

Unfortunately ospfv3 will not work if queue is set on the same interface.
This bug will be fixed in next version.

zajDee · Mon Mar 30, 2009 1:49 pm

Well, I'll have to set up routes manually for now.
Anyway it's good to know that ospfv3 does not like queues

And my last question follows...
By "next version" you mean "sometime in the future" or "in 3.23"?

Thank you very much.
