The more complicated language like ‘subsumes’ is gone and only one filter rule is required to use the filter in the routing process – the ‘select-rule’ syntax is gone. If the current filter documentation represents the newer style, there are several differences in the format. MikroTik – RouterOSv7 first look – Dynamic routing with IPv6 and OSPFv3/BGP – I wrote an article in late 2020 on IPv6 with BGP/OSPF using beta2 and captured a few screenshots that aren’t in the online docs anymore. The original v7 routing filters were very complicated to work with and had esoteric terms for operations like ‘subsumes’ and required ‘rule’ and ‘select-rule’ config to actually reference the filter in the routing process.
Technically, it already has been for one hardware platform…
If you don’t already use it, the MIkroTik v7 BETA forum () is a fantastic source of information
