BGP peering with MS 8075

Question

Hello

We have a peering with MS though public IXs DE-CIX on multi location (Frankfurt and Dubai) , but having issue that the we are receiving full route table with big blocks, for AS8075 on both peers, which causing conflict with traffic and high latency toward some destinations .

for example : the subnet 20.33.176.0/24 located in UAE, but received on routing table as 52.96.0.0/12

from both peering locations with same BGP attributes, causing the path to be through Frankfurt while it should be through Dubai ( if /24 shown in BGP) .

this setup is implemented on ISP, did anyone faced such issues and how could be fixed

regards
