we have 2 upstreams: Adamo + Telefonica
RETN has direct transit with both
in our routing tables, we see RETN routes with 2 hops for both (Adamo and Telefonica)
In the RETN looking glass, they are sending us the traffic via Telefonica.
But our Mikrotik is responding using Adamo.
Why we dont respond using the same link that we receive their traffic?
