I have connected to two BGP peers and getting the same IP prefixes. Now, I want to manually set the distance for the all prefixes of specific instance. I tried several filters to reduce distance 200 from 15 but failed. Please help me with this. Thank you.
Please check the attached image.

these prefix are dynamic and you can not modify manually it,
add a bgp input filter than auto change the distance for specific BGP peer, when imported on memory
Just curious - why not change weight or localpref to accomplish this?
are you trying to do a load balance? if yes, then as_path prepend can be applied
