ExhibitYou want the R1 and R3 routers to forward traffic destined to the 203.

To influence the path taken through an autonomous system, the Multi-Exit Discriminator (MED) attribute can be used. By setting a lower MED on R2 for routes advertised to R1 and R3, it will make the path through R2 to the 203.0.113.0/24 network more preferable.
