Hello @DellBananaALK 

Configurations seem to be good.

Using the Null0 interface for route summarization is good... However, be cautious with using it for the whole subnet '172.16.10.0/24'. It might be better to use a more specific route to avoid accidentally blackholing legitimate traffic.

[DellBananaALK]

I'm looking for best practices and any recommendation to or changes ? 

[MHM Cisco World]

I see your topolgy but I dont know where is LO connect abd prefix.

Also how you use bgp multihop and fall over bfd? Yoh need bfd multihop

[DellBananaALK]

ISP is not far,  it's very close by and I think less few miles or walking distance
It's safe to use 
I added the second route-map and add permit and made it blank so it allow everything doesn't make any changes so much it's allowing everything

Question was route-map with access-list you don't need a second route-map to allow?
it's different from prefix-list
