am = adjacency manager. Since NXOS is a modular OS, different processes/services source routes to the URIB, and AM is one of them. OSPF, BGP, other RPs, HSRP, etc also feed their routes to the URIB. AM really only feeds directly connected host prefixes (/32) to the RIB (ie, for each resolved ARP entry). These entries are not shown in sh ip route by default (unless you're running very old code) - I assume you are using sh ip route am to see these? If so, completely expected. We can take the discussion to cisco-nsp or offline if you need more information. Hope that helps, Tim At 09:36 PM 10/29/2010, Colby Glass uttered:

I've read that am = adjacency module or adjacency manager. The words mean less to me than why I seem to be learning this route from a phantom module/manager/interface with no visible explanation.
I can try on c-nsp as well. Thought NANOG might be a better choice.

a better place to have asked this would be c-nsp

We're seeing an AD of 2 on some routes on our Nexus 7k. I can't find anything (Google) to indicate where this value is coming from. Also unable to find out what "am" mean (adjacency module?). Does anyone have an explanation for this one?
