Why R3 does not send MED attribute to other BGP peers?

[kolunloluk]

Hello everybody!
Please help me as I got stuck in my home Lab with BGP MED value.

Even though I`ve configured metric (aka MED) value in redistr - it does not show up on R2 (iBGP) or R4 (eBGP). According to rfc4451 it MUST propagate this value at least to iBGP speaker but in fact - it`s not. I don`t have any filters, "extra configs" on other routers. I strongly believe that it will work out via "route-map" as usual but in this case I`d like to see normal behavior without extra manipulations or complications

Hello @kolunloluk 

To clarify please, share your configuration with the minimum info about your MED config.

You should have a route-map with set metric x command
