We use this filters like this
match to $provider1Main set metric low
match to $provider1Backup set metric middle
match to $provider2Main set metric high

Hi Gregory,
we have multiple redundant FE upstream peerings to the same AS. So I guess
the best solution would be in our case to let the upstream provider assign
different community flags for packets passing each FE line which we can use
for outgoing route preference decisions.
Other ideas are welcome ;-)
Use the MED to balance the prefixes over the various links.
You can use communities or other filter rules to tip them.
This would also allow you to split the sessions to multiple machines.
If you have a larger network you could use ospfd and distribute a default
route from each bgp router. Then you get multiple outgoing pathes from
within ospfd.
