Peering Troubleshooting

["K. Graham" <kim () servergnome org>]

Just a quick quesiton.  I am looking for some information as to "How to
troubleshoot Peering".  If anyone can point me in the right direction I
would appreciate it.  

I have been able to find alot on what it is, how to set it up, where to
set it up but nothing on how to troubleshoot it if it is down, a degraded
service, or being overloaded due to a ddos.

If you like contact me off list.  I can make a summary of the information
if it is wanted.
