Hi, we use BIRD 2.0.7 BGP VPNv4 and need to filter extended BGP communities on ingress. Config snippet:
define PFILTER_RT = [ (rt, 65100, *), (rt, 65101, *), (rt, 65102, *) ]; filter IMPORT_FILTER { bgp_ext_community.filter(PFILTER_RT_MASTER); accept; } protocol bgp 'my-router' from VPN4_S3_TPL_BGP_DEFAULT { vpn4 mpls { import filter IMPORT_FILTER; }; } This is working as expected. We discovered that RO communities are filtered too (not a surprise) and we extended the definition: define PFILTER_RT = [ (rt, 65100, *), (rt, 65101, *), (rt, 65102, *), (ro, 65100, *), (ro, 65101, *), (ro, 65102, *) ]; We dont need to filter strict for RO communities and best would be to allow all. Is there a better way to allow only defined RT and all RO communities? Are there any plans to allow wildcard or range in these definitions? Like: (ro, *, *) or (ro, 100..300, *) Another question: Are other extended community sub types beside RO and RT (as defined in RFC 7153) filtered by function bgp_ext_community.filter() ? Thanks in advance Regards Tobias
