Funny, I was just at your IPv6 sight this morning while researching
multihoming scenarios. "That name sounds familiar."

I agree. But swapping providers is not the default answer in some
environments. I work in an enterprise with multiple GE circuits from
multiple providers to the Internet. The lead time on calling up a different
carrier and saying "I need a gigabit connection to the Internet" would
probably be 90-12
Assuming that he has provider independent space (why run full BGP feeds if you
are not multihomed?), then, actually it's about on par and less disruptive in
general. Add new provider, wait a day or two, then disconnect old provider.
If he's using provider assigned space, then, the big hurdle is s
I'm not argueing that at all. But it wasn't relevent to the question at
hand. And depending on the scale of your business dumping providers is not
something done on a whim. It's not like your fed up with DSL and want to
convert to Cable.

Quick question, are you running with a default route from your
provider? If so, you're better o

I've had this happen with providers that do know how to handle BGP. Just
because you peer with 3356, 701, etc, doesn't mean operators can't make a
mistake. I've even seen this happen due to some wierd BGP behavior cau

I would simply monitor PPS on those links and set a threshold which will
kick off an alert at least. If your scripting savvy, other tools such as IP
SLA and EEM on Cisco could be used to automate the failover. Juniper also
has a similar scripting tool that can probably do the same. I've had this

you trust they will forward your packets
