Hi list.
I'd like to setup my default routes to the Interwebz to be conditional on
reachability of something on the Interwebz. I got two different ISPs (no
BGP). I'm trying to figure out what would be a reliable object to track?
Meaning, it's probably not reasonable to track my ISPs default

I'd rather send him to something more open like kernel.org; anything
but Google's DNS. Google's DNS is a little too nefarious for my taste.

Would it be more reasonable to track a root DNS server that is available via
anycast?? Something like 192.33.4.12?
Not sure how accurate this is:

I think that good is all relative to what you are most likely to be
able to reach from wherever your location happens to be!

I'm in the process of trying to setup bgp peering with Cymru to receive
the bogon route list. I've got everything setup using the examples they
have listed, but can't get the filtering to actually work on the
incoming bgp. Using a Cisco 7200 router. Any off-list help would be
appreciated.
Can you give us a little more details around how you're trying to convert the
BGP routes received into an ACL?
While we're on the topic, I'd really love for the Team Cymru folks to turn
their bogon list into a Flowspec feed hint hint ;)
Sorry for the top post, I'm on my BB.

To be absolutely safe, choose 4-5 of the ideas, track all of them and use a
composite track object to combine them :)
You can find a lot more details (including the oscillating routing problem)

As he said, there are examples of how to implement this on the Cymru
website, see:
Tarig,
I am not quite sure what you mean, but it sounds like you're suggesting
that different pieces of your network are fragmented across different
connections to different ISPs.
Depending on what exactly the problem is, the solution would be either
(a) to get a provider-independent IP
I've been getting repeated junk emails from an XO customer and
reports to ab...@xo.net are going unanswered and the problem is
unresolved. Is there anyone who has a better contact who can take action
on this issue? Offlist replies welcome.
Thanks.
