BGP w/ route filters issues

Fri Dec 14, 2018 6:56 pm

I'm struggling on getting route filters working properly in >=6.42

I can't seem to discard ranges. ie, if there is a 10.100.5.0/24 subnet, I have to put exactly 10.100.5.0/24 in the prefix, I can't get it to work putting in 10.0.0.0/8 in prefix and setting prefix length to 8-32.

BGP still advertises the 10.100 route.

I do have the out filter in the bgp peer.

What am I missing?

Without actually having a look on your config it's hard to tell.
Please provide the output of /routing filter export and /routing bgp peer export hide-sensitive

out of frustration I nuked all the rules and re-added and it's working. idk what's happening, I have ~150 mikrotik's in the field and never run across this exact issue before.
