Hi, I tried to setup new environment using FreeBSD11 amd64 on vmware and everything work without a problem, I didn't see any error or interface issue like on routera and routerb. Let's say that new router we called it routerc and routerd. I try to create ospf session between routera to routerc, routerb to routerd and the neighbor is appear, everything is normal. I don't know why but the ospf hello packets are not sent by routera to routerb or vice versa. What I have to do?

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

Hi Keenan and Ondrej,
I already update the configuration as your advice but the still couldn't be established, here is the new configuration:
Hi
You have 'type broadcast' set on router A while default is used on router B (which would be ptp for /30 network).
But i am not sure if that is the only problem.
You can try to run tcpdump on bge0 to see if there are Hello packets from both routers.
