I'm wondering how many of you who are multihomed also add default

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

remotely (in-band). The downside is that I might pass traffic for
non-existing destinati

Back when I was in the ISP world I installed a default route pointing to a
data capture machine. T
Usually, when this is done, it is an adjunct to providing connectivity fast
while the table is loading on a connection reset.

We filter out default routes from our upstreams, but m

If you have no IBGP between two sites and your prefix is a large /16 on side

Back when I worked for the DNC we ran into a problem with the TCA
Long time I had the same opinion, however, if someone operates a network
with multiple upstream providers the operator should be able to afford a
proper out of band console access which solves this issue completely.
I would only accept a default route on Uplinks where I am only receiving
