Hi Alex, Can you supply configs? I've got a RB2011 and a CCR1036 doing broadcast BFD with seemingly no issue.

Hi
Just an update seems like I spoke to soon, completed my upgrades of my other boxes and tried to put 4 nodes together ... failed around the 60- 70second mark :(

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
