Hi all,

I've been working on this little problem for few days but have not been able
to crack it.
Can anyone shed light into this please?

        R1============R2
            = =
              = =
                = =
                   = =
                     ========R3

R1 is in AS 1
R2 and R3 is in AS2

R1 is advertsing a subnet eg 1.1.1.0/24. Normally R3 will have to path to
the network, first via R1 directly and second via R2.
And the preferred path is via R1 because the administrative distance of the
route learning from R1 is 20 while the route learned via R2 is 200.

The challenge of the excercise is to configure R2 so that R3 would prefered
the route it learned from R2 without additional configuration on R3.
