Hello!
I'm trying to inject flowspec routes from bird to Juniper MX box:
route flow4 { dst 109.68.40.15/32; proto 17; dport 53; } { bgp_ext_community.add( (generic, 0x80060000, 0x0 ) ); };
route flow4 { dst 109.68.40.16/32; proto 17; dport 123; } { bgp_ext_community.add( (generic, 0x80060000, 0x000098968 ) ); };
The second flow specification should apply traffic-rate to traffic, but on Juniper these two flow routes have the same community:
Hello
Note that the traffic-rate community uses floating point and not fixed point representation, so 0x98968 is almost zero. See

(It also contains a link to a FP32 convertor.)
