I don't have much experience in this field. Some Extended communities are defined in ryu.lib.packet.bgp. I guess you'll need to set extended attributes in Path.pattrs. VrfTable.insert_vrf_path may serve as an example. > Moreover i would like to modify some bgp decisions, like announcements > propagation that should be done using certain criteria.

Hope this helps. -- IWAMOTO Toshihiro _______________________________________________ Ryu-devel mailing list Ryu-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ryu-devel
