[c-nsp] BGP Med and outbound metric

[Matthew Huff]

rtr-feed2 is on our side. What I'm attempting to do is to pref rtr-feed1 over rtr-feed2 (hence the 200 metric).

I'm also seeing the metric of 0 on the "show ip bgp neighbor 10.151.0.82 advertised-routes".

Is the "rtr-feed2" your side or their side?

You can only see the results of an outbound route-map on the other side.
The metric you see on your side is the one you box knows about.

Are you sure they would accept the MED setting? It's quite normal to
clear this inbound to enforce some standard policy.
