set bgp_med

[Christoph via Bird-users]

Hi,

in the config snippets below I added the export filter, see the "<<<<" 
signs. The goal is to set the med.

When running "configure" this change triggers this warning:

<WARN> Channel nextlayer_ndc1_v4.ipv4 hits route export limit (1), 
action: disable

Which suggests that this config change causes a misconfiguration and 
route leak, correct? I only expect to announce a single prefix.
How would you actually set the med instead?

thank you!
Christoph

        ipv4;

        accept;
