I often opt to leave one or more default routes configured with low
priority (lower than BGP). The thinking is that if there is a fault with
BGP, the router will still operate and the fault can be corrected
remotely (in-band). The downside is that I might pass traffic for
non-existing destinations an additional hop and put the load of
generating an ICMP unreachable on someone else's router.

I'm wondering how many of you who are multihomed also add default
routes pointing to your providers from whom you are receiving full feeds.
If so, why? If not, why not?
Thanks,
