Naturally, you'll want to clear the bgp session because networks in the
table before a filter is applied will remain until you do.
What's more, your route-map is applied to your "redistribute ospf" line.
This will not prevent advertisements from a peer from showing up in your
table. While I haven't looked at all of the requirements surrounding
this specific task, you might consider a distribute list. For example:
Neighbor 150.50.5.69 distribute-list 6 in
!
Access-list 6 deny 150.50.5.64 0.0.0.31
Access-list 6 permit any
!
Always remember to clear the session when you apply a filter.

Guys,
In the last part of point 6, it ask to block the 150.50.5.64 network
from being in the BGP table. I configure my routers as shown:
I created the route-map to filter the 150.50.5.64 network. but it
still shows in R5.

However, it still show in R5
