[c-nsp] Verifying BGP Propragation

[Paul Stewart]

Hi Michael...

When I do show ip bgp nei x.x.x.x advertised-routes I see the prefixes
leaving our system to the upstreams.  According to the upstreams both are
making it through their system which I can verify with one upstream on their
looking glass (level3).  With the other upsteam I do not see the
advertisement on their looking glass however this upstream (Bell Nexxia) is
apparantly directly connected to Hydro One Telecom which is where our
downstream gets their other pipe from.  So I'm told by Bell Nexxia that we
would be an AS hop further away (which makes sense).

At this point I'm unable to confirm or see the routes for our downsteam
(which by the way is AS14456).  We are AS11666.

Thanks,

Paul

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?

shwo ip bgp neighbors x.x.x.x advertised-routes

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
