Hi Ivan, thanks for taking a look at it.
But I have it done at my lab, and Well it seems not to be working, maybe a
little bug in the Version IOS (tm) C2600 Software (C2600-J1S3-M), Version
12.3(18), RELEASE SOFTWARE (fc3)

I'm trying that later on another Router
Thanks again
Victor.-

1) agree
2) Your configuration seems act like in example.
ip access-list standard filtering-RP
  permit 50.0.0.2
  deny any

permit 50.0.0.2 - means that R2 should subjected by filter.
deny any - any other routers must "blindly" accept by MA, the same as deny
R4
in this case.

ACL filternig-group strange for me.
    ip access-list standard filtering-group
     permit 224.1.0.1
     permit 224.1.0.2
     permit 224.1.0.3
It permit all example-groups.

Therefore MA filter R2 all group except 224.1.0.(1|2|3) and "blindly" accept

all group from R4 (in example) and from any (in your case).

If we want to reach the task we can simple delete ACL filtering-group. And
ip access-list standard filtering-RP
  permit 50.0.0.4
  deny any
