BGP filtering question

I am trying to migrate from RouterOS BGP setup.

I have filter rule like

chain=BGPINFilter-common prefix=10.32.0.0/14 prefix-length=14-32 invert-match=no action=discard set-bgp-prepend-path=""

basically it drops all prefixs for 10.32.0.0/14 down to /32's

how can I do this on the pa.

I have something like this

set template ybopa config network virtual-router vr_ybopa_default protocol bgp policy import rules BGPINFilter-common match address-prefix 10.32.0.0/14 exact no

I presume this means it will drop 10.32.0.0/14 and anything with longer prefix

and if I select exact it will only match 10.32.0.0/14

Hi Alex,

Yes, your understanding is right on this.

So it would reject all the prefixes from /14-32 if exact match is no

Also be little careful to have allow rule below deny for rest of the networks, it works in top down approach.
