Colin, > Perhaps this is some internal SDN thing that leaked publicly ? You are right ... attribute 243 is Contrail's OriginVnPath attribute useful for more complex service chaining scenarios. https://github.com/Juniper/contrail-controller/blob/82cdb6afee49b39e54364f18be8eeca725dd76f4/src/bgp/bgp_attr_base.h With that let's also not forget about attributes 241 and 242 used for multicast edge replication. The work on draft describing those last two temporarily allocated attribute codes is currently being resubmitted. The good news is that they should not be leaked as they are to be send in their dedicated SAFIs so unless peer exchanges right capabilities they should be quite contained. https://github.com/Juniper/contrail-controller/blob/82cdb6afee49b39e54364f18be8eeca725dd76f4/src/net/bgp_af.h Thx, R. We also found an interesting unknown attribute, code 243. This appeared > at all our collectors but only during June 2016. We're not sure what it > is.
