One of the complexities that comes up when you manage a large number of routers is keeping their configs all in sync. Specifically any commonly access-lists that are used. I wanted to solve this using the Mikrotik API, but that has changed formats between v6 and v7 so its a bit more complex to cover off both versions with one codebase at this time. However by pulling instead of pushing, I was able to massively simplify the process.
I recently acquired a Mikrotik CCR2004-1G-12S+2XS, which is a much faster, much more modern router than the CCR1036-8G-2S+ routers I was using previously. This gives me enough router CPU power to run BGP with full routes, and RPKI validate the routing table.
