It is supported here: https://github.com/Azure/sonic-buildimage/tree/master/dockers/docker-fpm-frr/frr/bgpd/templates Please look inside of the directories. Ask me here, if you have more questions.

hi pavel, please check #4733, we can't find keywords BGP_ROUTEMAPS in sonic-swss/doc/Configuration.md(Only BGP_NEIGHBOR & BGP_PEER_RANGE found), right?

Hi @tim-rj Yes, you're right this is not supported. But we have this proposal sonic-net/SONiC#544
