The memory leak was solved a while ago and Mikrotik has fairly short release cycles. We have extensive inbound and outbound filters on our eBGP doing most of the normal things that you would do on a cisco. The IPv6 filters must be built via the terminal to avoid limitations with the current GUI but they also work very well
In some ways, I find the MikroTik RouterOS routing filter syntax a little more powerful than Cisco's route-maps. As routing filters work the same way as firewall filters, you can group rules in "chains" and reuse parts of your filters in other filters by jumping to another chain. This could be used, for instance, on a peering setup, where you have a number of rules per peer but also some common filtering for all peers, or to handle specific and generic filtering for your customers. I haven't yet found anything that I missed being able to with filters, at least with BGP. With other routing protocols, it's another story. Regards, Allan Eising
