Hi Ondrej,

I already tried to change the configuration use broadcast on routera and
routerb but still same. I use tcpdump as your advice and I can't find any
ospf hello packets that sent to neighbor or router it self, here is my step:

1. on routera (, do:
    - tcpdump -vvXn -i bge0 ip proto ospf, no result (empty).
    - tcpdump -vvXn -i bge0 host and ! arp
2. on routerb (, do:
    - tcpdump -vvXn -i bge0 ip proto ospf, no result (empty).
    - tcpdump -vvXn -i bge0 host and ! arp and ! proto icmp

Please see the tcpdump second test on pastebin below:


Any other clue please let me know.
Thank you..

Best regards,
David S.
