You can do some show commands on your side to verify that you are sending
them your prefixes, Do es either route show up when looking at the looking
glass?

Hi there...

We have a downstream connection that I'm trying to confirm is actually
appearing through two of our pipes.  The downstream has good connectivity
through other providers so a lot of their inbound traffic is closer than
what we are offering them.

When I try various looking glass sites and route servers our path doesn't
showup most of the time, if any of the time.

How can I verify that filters are not blocking their advertisements from us
effectively?  I have talked to both upstreams and they confirm that
advertisements are showing up on their edge and passing through....

Seems like a really basic thing, but I want to make sure...

Thanks,

Paul
