Hi Group,

I have a question about BGP MED, the scenario is the following:

                                                             --------------EB
GP----------------------R4
                                         OSPF |
|ibgp
     NETA
----------R1------------------------------R2------------EBGP-----------------
-----R3-------------EBGP-----------------R5

R1 Tx NETA to R2 by OSPF and R2 Tx NetA to R3/R4 by EBGP. R3 and R4 Rx NETA
with the IGP (OSPF) metric. When R3 Tx the route R5, R5 Rx the route with the
metric 0. I understood it, but I have the following question:

If I apply a route-map from R3 to R5 with set metric-type internal.......This
would cause BGP routes to carry the internal IGP metric as the BGP MED?

R3/R4 carried the IGP metric without a route-map in R2.

Could you help me, please?
