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 (10.22.40.17), do: - tcpdump -vvXn -i bge0 ip proto ospf, no result (empty). - tcpdump -vvXn -i bge0 host 10.22.40.18 and ! arp 2. on routerb (10.22.40.18), do: - tcpdump -vvXn -i bge0 ip proto ospf, no result (empty). - tcpdump -vvXn -i bge0 host 10.22.40.17 and ! arp and ! proto icmp Please see the tcpdump second test on pastebin below: http://pastebin.com/cp6PU9d9 Any other clue please let me know. Thank you..
