Hi Daniel,

I reviewed the code and think that OpenBGPD supports only the behavior of
Cisco routers when bgp deterministic-med is disabled, cp. 
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094925.shtml
Cisco determinsitic-med attribute description .

Is there anybody who can confirm this?

Uli
