Greetings. I've got a fully OSPF routed network. Over 65 "Core" sites. On top of this, I've applied MPLS to facilitate in L2VPN services.
Since we started running MPLS (~6.6ROS) I've had this problem where the MPLS forwarding table will come out of sync with the OSPF driven local routing table. Causing traffic to be routed incorrectly.
When this happens, A reboot of the router will fix the problem. However I can also build a local binding label, Apply it, Then remove it (Forcing the forwarding table to reload) and the issue is then resolved. This is a lot quicker then rebooting the entire router.
I've submitted the issue to Mikrotik in the past, But their response has always been "Please upgrade to $LATESTROS and let us know if the problem continues". It always does. And I can never get the problem to occur on a particular router while it's running the latest ROS build.
This also has occurred on both CCR's and RB2011's. Of all mixes of ROS from 6.6 Up. However I don't have any coresites running 6.37.2 yet. But I suspect it'll have the same problem as well.
Below are screenshots of the problem.Has anyone seen this, Or know of a fix?
And then after a reload of the forwarding table by temporarily applying a local binding.
