If the value is what it is supposed to be, then I guess it will work. I was
just bringing up this possibility:

Suppose R2 and R3 are in AS65000 and each have a learned route through
AS100.
R2 sets local pref to 200
R3 sets local pref to 300.
R2 and R3 are ibgp neighbors so R2 prefers the path through R3.

You want to prefer R2 and you think you can set outbound localpref on R2->R3
to accomplish this.

This wont affect R2's local pref, only R3's....right?

So R3 will have higher local pref (400>300) pointing to R2
and R2 will have higher local pref (300>200) pointing to R3.

So the packet bounces between R2-R3. This was my theory, I haven't tried it.
