> You are mixing SRC_ASN with TARGET_ASN in the same field.

I want to point-out that by forcing the first field to be "src_asn" as
you are suggesting, would make one intended use of -large- not possible,
for ASN1 to tell ASN2 to do something with a route as it applies to ASN3.
eg: ASN2:ASN3:action, ie: apply "action" (such as prepend) defined by ASN2
to ASN1's route when advertised to ASN3.

We have improved it.
