Hello bird users, I just started to test bird 2.0 and converted the existing bird 1.6 configuration to bird 2.0. I compiled bird 2.0.0 on my fedora test VM and got it running. But when I use path prepending in BGP (the same way I did in 1.6) bird throws an error and does not export the route. Does anyone have the same problem? Thanks, Daniel Configuration: template bgp generic_bgp { local as 202739; enable route refresh on; keepalive time 10; hold time 30; } protocol bgp vultr from generic_bgp { neighbor 2001:19f0:ffff::1 as 64515; ipv6{ next hop self; import keep filtered; import filter upstream_as64515_in; export filter upstream_out_test; }; multihop 2; password "xxx"; } filter upstream_out_test { if net = 2001:678:1e0::/48 then { bgp_path.prepend(202739); bgp_path.prepend(202739); bgp_path.prepend(202739); bgp_path.prepend(202739); accept; } reject; } Log: Dec 20 17:47:51 bb1 bird[1370]: filters, line 110: Can't prepend to non-path
