Hi Plamen,

Here is the ifconfig for bge0 both on routera and routerb

I don't know why routera couldn't sent ospf hello packets to routerb vice versa.
You can find on my previous post (pastebin) for the tcpdump resulst.

Thank you

Hi David,

Can you please provide us with the output of 'ifconfig bge0' from both machines?

It would also be helpful to get ping router-a from router-b and vise versa. Does this work?

Thank you in advance.

Best,
Plamen

Hi,

After installing a 1 server with FreeBSD11 and configure BIRD with minimum configuration I saw that error "invalid argument" for bge0 is still appear but not for igb*.

This takes more than 4 days, still confusing.

Does netmap cased this problem? Netmap is enabled by default on FreeBSD11 (CMIIW).

Thank you

Hi Ondrej,

I have no firewall enable and it's not work on all card. I have 4 port 1gbe broadcom and 4 port 1gbe intel I350 chipset based.
The clue I only have is ospf not sending hello packet between routera to routerb vice versa, both of server use HP DL360 Gen9 FreeBSD11.
Both router has multiple bgp session and receive full route from the internet.

It's weird, when routera able to send and receive ospf hello packets from and to routerc vice versa, both of them are FreeBSD11.

I'll try to reinstall the OS and configure ospf first and then one by one configure the bgp.

So, it's only happen to me? :d

Thanks anyway.

It seems like some specific problem in your setup. Perhaps firewall or
insufficient privileges? Does it work with different network card?
