We have OSPF + BFD running on CCR1036 and CCR1009 on both RouterOS 6.5 and 6.19. On the CCR1036 with 6.5 it has been stable for 18months now and they have passed over 600TB of traffic. It seems it is broken every few releases.. Prior to 6.5 it was unusable for us. On Sat, Feb 7, 2015 at 9:43 AM, Alex Samad - Yieldbroker < Alex.Samad@yieldbroker.com> wrote:
Update
So I have upgraded to 6.26 and firmware upgrade to 3.22
and now it seems to be stable !!! I have a OSPF BFD link up for 5min... way longer than what I was able to get before

Hi Alex,
I did a test with a CCR 1009 v6.24 and a CCR1016 v6.26 linked with an SFP direct attached cable and setup ospf with BFD on the link and found that it dropped regularly every 90-150sec or so. Just a lab setup with no firewalls.
Normally I do not have any issues with OSPF without BFD.

Hi
I have a few CCR1036-8G-2S+, (6.22) I tried turning on BFD with OSPF. My first hurdle was BFD doesn't work by itself ! I then associated it with a OSPF interface, which had 4 nodes on it. Turned it on all 4 nodes.. worked for a while then up / down flapping ... I ran some tests sending flood pings down the line, no missed packets !
My final test, 2 of these boxes side by side, 1 cross over cable. Turned on OSPF + BFD, started to fail :(
I have a nice simple firewall rule 10 ;;; Allow BFD chain=input action=accept protocol=udp dst-port=3784 log=no log-prefix=""
I do have a drop invalid before it, but that should affect it and for a period of time BFD does come up.
I have it attached to one of my BGP peers on a ROS VM, it seems to work fine. So I'm leaning toward an issue with CCR's
So anyone else using BFD with CCR's and OSPF ?
Alex
