bird 2.0.0 issues

Hello, I just installed bird 2.0.0 on a test machine to try it out and I have some issues: (CentOS 7 / kernel 4.14.5-1.el7.elrepo.x86_64) 1) the kernel protcol sees no routes (both ipv4 and ipv6) and doesn't export any routes 2) each time I change the config and do a 'birdc conf' it resets all BGP sessions and logs bird: Cannot reconfigure channel XXX.ipv4 bird: Cannot remove channel XXX.ipv4 bird: Restarting protocol XXX 3) can't establish BGP with bird 1.6.3 if I have add paths on; on the session - 2.0.0 says: "BGP Error: Malformed attribute list" and 1.6.3: "Socket: Connection closed". add paths on; works between two bird 2.0.0. Could these be caused by kernel or *lib versions or are these bugs in bird? Thanks, Radu
