Hi all I made this observation while trying to set up ospf routing. (6.37.1)
Mikrotik Router: LAN 1: 192.168.57.1/24 LAN 1: 10.247.8.1/29 LAN 2: 172.19.3.1/24 OSPF Router id is set to: 192.168.57.1 bird Router: LAN 1: 192.168.57.200/24 Lan 2: 44.142.200.36/26 I set-up ospf on both routers. The mikrotik can see the hello packets from the bird router, but not vice versa. I sniff the interface and see, that the mikrotik is sending the hello packets with wrong source: 10.247.8.1 I disable 10.247.8.1 for testing and disable, enable the ospf instance on the mikrotik. ospf hello are still sent with source 10.247.8.1 even this ip not being active anymore. I reboot the mikrotik. ospf hello are correctly being sent from 192.168.57.1. I re-enable 10.247.8.1. ospf hello are still being sent from 192.168.57.1, fine! I disable, enable the ospf instance. source is still 192.168.57.1, fine! I reboot the mikrotik. hello source falls back to 10.247.8.1 and ospf is not working anymore as the bird router cannot reach this ip. I try to move 10.247.8.1 to a local 'loopback' bridge, as found in some tudorials. I have to bridge the loopback interface with LAN 1 for my local routing to work. But this again makes that IP visible on lan 1 and ospf grabs this ip after a reboot. Some testing by adding some more random secondary IP addresses reveals, that the ospf service grabs the lowest IP that is present on the interface during boot time. Am I missing something? How can I set the source ip for ospf hello packets on an interface with multiple ip addresses? -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
