V7 OSPF accept out filter - causes redistribute connected

RouterOS Forwarding Protocols
1

V7.9.2 I’ve found that if I set an OSPF filter with a general accept rule such as:

if ( dst-len > 0 ) { accept}

or simply

accept

All connected routes are now advertised via OSPF even if no route types are selected in the Redistribute option and even if there are no interface templates advertising those routes. If I then remove the filter, route advertisements return to normal.

Is this by design that the route filter should override the redistribute option and template functionality or is it a bug?

Many thanks,

Sam

routing filter and select chains in ROSv7 by design are used to control route redistribution. “redistribute” parameter was added back just for quick redistribution option without using filters.
