Anyone seeing BGP weirdness?

I know this post sounds like a noobish thing to ask, but I've got sites in
three different cities - Tucson, Arizona; Devnver, Colorado and Salt Lake
City, Utah, and all three of them can't reach certain IPs of our clients
whom we have IPsec tunnels to. In one case I can traceroute to 4.2.2.2 fine,
but the traceroute to the public IP of one of my clients dies at the second
hop, right after my ASA.

Is anyone else seeing general routing weirdness on the Internets, or at
least can someone point me at a good "BGP dashboard" site that monitors the
state of routing tables at various places?

Thanks,
Eric

I have not seen 'weirdness'.
You can check: http://www.ripe.net/ris/index.html
or telnet to route-views.routeviews.org and verify if there's anything strange
going on with your prefixes.

Also, http://BGPmon.net might be useful for you in this case. It will monitor your prefixes
from several detectors all over the world.
Alarm / Notification messages will be sent to you in case of suspicious
announcements or instability.

Hope that helps.

Cheers
Andree
