UUNET service

In the cisco router, if you configure a aggregate route under bgp, it will
be pointing to null0 to prevent this senario from happening. So my question(
not related to attitude)is:Is this because of the aggregation?

To me, that looks more like an outage (now fixed) on a customer network.
The 'loop' between 500.Serial2-11.GW4.BWI1.ALTER.NET and
core62007-gw.customer.alter.net, could likely be caused by UU's customer
advertising an aggregate route to UU, but not actually having a route to
the IP...so they default back to UU, and UU sends it back to the customer.
This was likely a problem on the customer's network, so why should UUNet
take a trouble report from you? Not only are you not _the_ customer,
you're not even a customer, and it's likely not a problem they can do
anything about. If it really were a UUNet problem, they probably assume
their customer will report it.
