[j-nsp] Setting IGP metrics in BGP import policies

[Rob Foehl]

I'm looking for an equivalent of 'then metric igp' that would actually 
work in a BGP import policy, specifically such that the resulting MEDs 
would be redistributed to iBGP neighbors.  'path-selection med-plus-igp' 
seems to be purely local, and 'then metric igp' is explicitly documented 
as only working in eBGP export policies, so I doubt even the combination 
would accomplish what I'm after.

The obvious answer would be to just set the metric explicitly in separate 
import policies, but that results in a lot of extra config.  Are there any 
clever ways to do this, or am I crazy for even trying?
