There will be no new routing feature in ROS v6.

Hi Mrz,
Any chance to have support for SNMP BGP4-MIB in 6.x?


Thanks.

YES PLEASE

They have to draw a line in the sand somewhere.

Keeping on adding features to version 6 is a waste of developer time, it is better to let the developers work on v7 which will be a massive release.

Clearly, its a BGP problem that will be fixed in ROS v7? How long until we can test?

Also, is the amount of RAM important with running BGP? I was told it wasn't, then I seen in this thread that it is. We are using the CCR1036-12G-4S model, with 16Gb of RAM

It looks like one or two of the cores is being maxed out to 100% while all the rest are barely used at all. WHY isn't it spreading the processing power over all 36, rather than hammering one core for BGP???
This does not sound like it is related to BGP at all.

IP forwarding is already spread across all cores on CCR's, for UDP everything is, for TCP it is spread on a session by session basis. If you have one or two cores maxing out when traffic increases, you must be doing something to the traffic that is no optimised for the Tilera architecture. Typically this is queueing or tunnelling.

What version of RouterOS are you running ?

Well, I'm at 6.29.1 now. Check out this Cacti graph attached. If there is any expert MIkrotik / BGP consultants out there, please let me know, as I really would like to assure things are running at maximum/best config.

What you have seen is actually the BGP table scan hitting one of the CPUs for 100%. Unfortunately, once you get a full BGP table (550k routes) on a CCR, the single CPU core can barely finish one run of the table scan before the next one is due, which is the reason why one core stays more or less 100% loaded all the time. So yes, this is related to BGP, and no, there is nothing you can do about it (other than filter away /24s to reduce table size), and no, Mikrotik will not fix this behavior with ROS 6. One more reason why people are really hoping for ROS 7 to drop soon.
