[LDM #XGK-778495]: Pull LDM data from specific sites

There is more than one way to do what you want.

One way is to allow the downstream LDM to receive all
NEXRAD2 data-products:

ALLOW NEXRAD2 ^downstream\.site$

but have the downstream LDM request only the data from the one
radar site:


Another way is to allow the downstream site to receive only the
data from the one radar site:

ALLOW NEXRAD2 ^downstream.site$ ^L2-BZIP2/KABX

and have the downstream site request all data:


This latter method has the advantage of placing enforcement at
the upstream LDM.

In either case, the downstream LDM's "pqact" configuration-file
can process the data-products using a generic entry.

Does this help?
