Re: Fastpath on vlan interface.

I'm a little talking to myself here :) To make the analysis a bit harder in terms of performance, if I read all this stuff correctly one has to have onnectiontracking on auto in order to get fastpath/fasttrack. On the other hand onnectiontracking seems to take cpu cycles, which is again not good for...

Re: BFD + OSPF + CCR1036 Issue

It is best to avoid BFD until v7 is released.
well, removed it for the time being, as I like stable :)
might try to run it in the future, if MT care to comment on the issue.

just as a "fun fact" note: RouterOS v6.36 on a CCR1036 speaking bfd on a single 1G copper link (OSPF) with a Cisco (IOS 15.2(4)S7) does seem to carry a (at least for now) stable BFD interface (29 minutes and counting)

finally the prefix-count can be checked for a remote peer IP like this:

What is the business reason to force the DFS on? Mikrotik should explain it really in details. There are rules that when radar is detected, the Ap should lower its tx power, sometimes, so there is not really necessary to leave the frequency. When radar is stopped, it can revert the tx power back to...

Re: BGP IPv6 route reflection

We'd a similar issue, as we were running two RRs we could easily show to MT it doesn't work as expected.
They told us we should wait for ROS v7 as this is the only way they would fix this issue.
ergo do not try to use MT as RR for IPv6 running ROS v6.xx
