[c-nsp] BGP Med and outbound metric

[Matthew Huff]

Ah. I didn't realize the "show" was before the route-map was applied. I was trying to make sure everything was setup correctly on our side before contacting the other ASN.

They may very well have something that zero's the metric.

This is also true when showing "advertised-routes", which just shows you
the routes from your own local table that being sent to the neighbor,
but before the route-map has had a chance to change anything. AFAIK the
only way of seeing what they receive is on their side.

This is also still relevant. Do you have an agreement with them on this?
