AS 25543 (ONATEL/FasoNet BF) --  you really want to advertise
reachability to prefixes you've learned from AS174 and AS5511
(upstreams) to your friends at WIOCC (AS37662) ?
They will send the traffic to you.

Short rule: whatever you learn from any upstream or peer - don't
advertise this to any upstream or peer.

WIOCC,
maybe just filter all routes from your customer with AS_PATH matching
".*
(174|209|286|701|1239|1299|2828|2914|3257|3320|3356|3549|5511|6453|6461|6762|7018|12956)
.*" or something similar ?
