BFD on 1.4.2

[Kristoffer Egefelt]

Hi,

I’m trying BFD with some Force10 S4810 routers, problem is that sessions only come up every 3 or 4 times I restart bird.
Also if Force10 routers are restarted, some times the sessions do not come back up.
Also I have to restart bird to get it to work - birdc configure does not do it.

I tried with the sysctl -w net.ipv4.ip_local_port_range="49152 65535” but this does not help either.

I’m not able to get more debug info from the force10 devices than this:

working :
