BGP flowspec support

Hello, am I correct in assuming that bird does currently not support sending bgp flowspec rules (RFC5575) which uses MP_REACH_NLRI attributes? In proto/bgp/bgp.h I found these lines: /* We don't support these: */ #define BA_DPA 0x0b /* ??? */ #define BA_ADVERTISER 0x0c /* [RFC1863] */ #define BA_RCID_PATH 0x0d #define BA_MP_REACH_NLRI 0x0e /* [RFC2283] */ #define BA_MP_UNREACH_NLRI 0x0f [...] Regards Max
