[quagga-users 13762] OSPF: *** sendmsg in ospf_write failed to 224.0.0.5, id 4350, off 0, len 80, interface dummy0, mtu 1500: Operation not permitted

[Matshidze, Calvin C]

Dear List,

I have implemented zebra and quagga for dynamic routing using IPTABLES and SNAT (to enable SOURCEVIPA) on SuSE Linux.

The configuration is as follows:

VIPA=10.81.250.211
Interface IP=10.144.184.77
Gateway= 10.144.184.1 and 10.144.184.2

The IPTABLES rule to make 10.81.250.211 the source IP for all packets is as follows:

iptables -t nat -A POSTROUTING -p tcp -o eth1 -s 10.144.184.77 -j SNAT --to 10.81.250.211

When I I start OSPF it start up fine but the OSPF neighbor do not connect and instead i see this message on the log:

"*** sendmsg in ospf_write failed to 224.0.0.5, id 4312, off 0, len 80, interface dummy0, mtu 1500: Operation not permitted"

Any ideas what I could be doing wrong which is causing the above error message?

Thanks a lot in advance

you probably want to disable ospf on interface dummy0 and have it operate
on just the physical interfaces. Also, bear in mind that OSPF is designed
to work with real interface IP addresses and if you do stuff like natting
or masquerading these addresses, it will almost certainly break in weird ways.

Incidentally, if all you're trying to do is create a reliable default
gateway, it would be better to do this with something like VRRP or CARP.

no idea. you haven't given much info about how your box is configured or
what you're trying to do. Anything which nats OSPF sessions is doomed to
failure. If you have interfaces with overlapping IP addresses, then that
will probably also cause trouble with OSPF.

Hi Nick,

Please find more info on what I am trying to do. I'm basically trying to have all the IP packets leaving the box use the source IP (10.81.250.211) instead of using the physical IP interface IP address (10.144.184.77).

Currently I have this working with static routes on the switch without OSPF - and now I'm trying to use OPSF and have static routes removed on the switch.

Here's how the box is configured:

Thanks for the advice Nick. All I'm trying to do is make dummy0 IP
act as the source IP for physical interface IP 10.144.184.77. So if I
disable OSPF on dummy0 as you suggested I should be OK I guess, right?
I plan to attempt it as u suggested.

no idea. you haven't given much info about how your box is configured or what you're trying to do. Anything which nats OSPF sessions is doomed to failure. If you have interfaces with overlapping IP addresses, then that will probably also cause trouble with OSPF.
