retaining goodness for backup routes

[dtaht]

I have a backup default route with a high metric. Keeping that route around would probably be useful.

Going through each speaker and determining the number of routes that I'm installing from it as a measure
of goodness, and keeping it's less good routes available in case the default route goes down might be a way to get there.

What I observed:

gw1 ----------------------------gw2
            |            |            |
           ogw1 .  ogw2 .  ogw3

gw1: 440 metric
gw2: 96 metric
ogw1,2,3 reannounce they can get somewhere with 192 metric

gw2 withdraws that route
1,2,3 pick up each others metric and retract but also go unreach

gw1 ultimately wins after the carnage is complete
