Speaking of which, lines like these:

  Routes:         374804 imported, 3 exported, 374801 preferred

are a bit "misleading". As my peer claims to only 2 routes being advertized by 
me. Being able to "refresh" those advertizements without completely restarting 
the respective BGP session would be nice.
