Re: Splat Pro Ospf As you can see from my previous message , the routing configuration is the same ; the issue was solved adjusting the multicast mac address configuration on the switch. the problem now ( and for this we disabled the ospf configuration) is that when one module ( module2) goes down ( rebooting a node or stopping the daemons ) there are routing problems on the other ( module1) both when it ( module2) goes down both when it( module2) becomes up. Is the same for you (if you have an OSPF config..) Regards Maurox |
