Aggrgating the p2p IPs which used on uplinks and downlinks

I have the network which is showing in fig. I am using a subnet for p2p for downlinks as well as uplinks ( 10.0.0.32/27) and it aggregated on R1. Does this work properly or there will be any routing issues because of the aggregation. I am sure if I don't use the aggregated subnet on uplinks it works not sure if I use it. Please let me know.

Regards,

Siva

We need to see more of your BGP config, but generally speaking there is no problem with aggregating the IP space. Just make sure your IGP has reachablility to them as well.

The only thing I am worrying about is see on R1 we aggregated the subnet  in BGP and using those subnet IPs on R2 and R3 for conneting to R1.
