Hi

Seems like sFlow-RT tool sends flows with local AS (65000) in AS_PATH,
although it is IBGP connection and it should just send empty AS_PATH for
locally originated update.

Such path is filtered-out by BIRD as loop prevention. It would be good to
report that to sFlow-RT to fix that, but as a workaround, you can enable
'allow local as' option in BIRD.
