Please post your /etc/ospfd.conf and the output of ifconfig here. OpenBSD 4.0 is old, could you try with something newer? (Note, ip forwarding and ip multicast forwarding are enabled) No need to enable ip multicast forwarding. /Esben
Re: ospfd: some machines stuck in 2-WAY/OTHER

One of the routers is a Cisco, all other affected routers and hosts are OpenBSD/i386 4.1-stable as of May 24th. The problem is that some machines establish an adjacency with some, but not all machines in that area. I think you network is just fine. From the output I gather that the three routers all agree that 10.0.0.6 is the DR and that the 10.0.0.4 is the BACKUP. This is 10.0.0.4 - it has FULL with all routers and the DR.

Re: ospfd participating in a stub area
On Wednesday 07 February 2007 00:53, Nigel Roberts wrote: Is it possible to configure an area in ospfd.conf to be a stub area? I have an area where all particpating routers (ciscos) are configured to treat it as a stub ie. router ospf 1234 ... area 1 stub ... What excactly is the purpose of this? Is it some cisco trick to save memory or does it have a real purpose? Normaly when routers form adjacency the network is not considered a stub network any more, hence it can be used to forward traffic. /Esben

The man page claims that your configuration is valid, but it doesn't seem to work. I will look into this. /Esben

I normally see the no buffer space availible, when trying to transmit packets on an interface where the link has gone down. That however is normally prevented by the fact that ospfd senses link changes. /Esben
Re: OpenBSD { future=PIM (DM-SM) } support or { only=XORP } ?

If you manage to convince XORP to do PIM please let me know, that might come in handy when trying to produce some code for a OpenPIMD project.

Yes, tiny baby steps has been taking in order to startup a OpenPIMD project, but don't hold your breath... Step one would probably be a PIM-DM, later on it can be expanded to support PIM-SM. If any one are interested in this sort of thing please chip in. I'm going to start playing with DVMRP now that I see I can use mrouted with our current PIM routers and hopefull get a tunnel up to transport the multicast traffic to a OpenBSD gateway. This doesn't create a PIM router but it does give me more features to learn/play with on OpenBSD which is always a goal of mine. I use mrouted myself on OpenBSD routers, and I really really want to replace them. If you want to play, mrouted is good enough - I mainly use it for multicast video streaming, and IPerf multicast test streams. /Esben
Re: Cryptographic authentication ospfd not working?
On Friday 28 October 2005 09:15, Egbert Krook wrote: Hi, Does anyone know if MD5 authentication in ospfd is known to be broken? In our test environment things work fine without authentication or simple authentication turned on, but as soon as we turn on MD5 authentication things break. We're using the snapshot of October 13th and a Cisco 3640 router (IOS 12.1(5)). If this is an unknown problem I will submit a bug report. I cannot reproduce this with ospfd from current and a cisco 72xx router, using your configuration... Could you provide a tcpdump trace? /Esben
Re: ospf/gre or bgp over ipsec instead of cisco?
On Tuesday 03 May 2005 23:47, Stephen Marley wrote: Can anyone forsee any problems doing this with the current state of ospf within openbsd? Or gif instead of gre perhaps? One of the things that usally comes back and bites you is the lack of multicast support (or buggy multicast support). All (well almost all) OSPF signalling is sent as multicast traffic. A gre tunnel should handle that fine, haven't tried it but it seems it's just a point-to-point device. The currnet state of ospfd should be enough to test your setup, and feedback from such a test would be greatly appreciated. /Esben
