Hey:
Manually speaking, you can always telnet to route-views.routeviews.org whic=
h is a restricted Cisco interface. Log in with username "rviews" and don't=
enable. From the prompt you can do all the "show ip bgp" commands you nee=
d to see whether or not your /24 is being announced via your upstream provi=
ders. As an example 'sho ip bgp x.x.x.x' where x.x.x.x is your /24. You s=
hould see the announcement originating from your AS over multiple providers=
that includes both of yours. If not, you know you have a problem.
Mike
