ospf and logical-system

mumulox

Hello,

I'm trying to run ospf between 2 logical-system in one olive but I don't know why it's not working.

My config is simple:

For routing between logical-systems do I need to connect two real interfaces with a loop cable even if I can ping from one logical-system to another? fxp1 and fxp2 are not bridged with physical interfaces.

Thanks

Seems like your OSPF interface are not defined properly.
Instead of <interface 0.10.10.1> use <interface fxp1.10> or whatever interaces are in use.
Hope it will help
Thanks
Robert

mumulox

no,it is not working. I don't understand if I need to connect fxp1 and fxp2 with a crossover cable or not, or the logical-router works by default .

zoidberg

I second what Robert said there.

If that still doesn't work, include some new ospf outputs so we can see what's going on. I haven't done logical systems inside of an olive before, so I'm not certain about the physical connectivity requirements. I thought you needs to loop the ports, but I really don't know.

I start olive with this command:

qemu olive1.img -daemonize -serial telnet::2001,server,nowait -localtime -net nic,vlan=1,macaddr=00:aa:00:60:00:01,model=i82559er -net tap,vlan=1,ifname=tap0,script=no -net nic,vlan=2,macaddr=00:aa:00:60:00:10 model=i82559er -net nic,vlan=2,macaddr=00:aa:00:60:00:20,model=i82559er -net nic,vlan=2,macaddr=00:aa:00:60:00:30,model=i82559er -m 1024

tap0 is bridged with eth1, tap1 bridge with eth2 (phisycal interfaces in my pc).
If I connect the 2 interfaces with a crossover cable it will result a layer2 loop.
My problem is that multicast traffic is olny in out direction. Ping works between the 2 logical-routers.
I don't have a problema with multicast in olive because I cand run ospf between a cisco router and olive

Aldur

wasn't there a problem with qemu in the old days that prevented ospf from working due to multicast problems?

Yes, it was, but ospf works ok between my cisco router and olive
