BGP announcement

Sun Feb 27, 2022 11:55 pm

Hello,

I am running RouterOS v.7.2rc4 (but it was the same on v7.1.3) on a CCR2004.

When I configure an eBGP session (receiving a DFZ full routes) and after the device has established the connection, if I modify the prefixes to be sent by modifying the "output filter" to point to my list, the router does not "refresh" the routes to be advertised unless I manually teardown and re-establish the session.

Is this a known problem of RouterOS v7 and is there a fix for it or am I just doing something wrong?

I anticipate people asking about my configuration, below is a copy of the current test configuration.

I appreciate any hint.
