Hi Edwin,
In case anyone else reads this, we are talking about this post right:

You are correct. In this example, R2 will create a LSA type 5 directly which R1 can learn and a LSA type 7 that R4 will learn. There’s no need to create a LSA type 7 and then translate it into a type 5, that’s why the P-bit is disabled.
