Well, all look okay except:
> ^300$ = orignating from 300
I believe this actually means from the CONNECTED AS 300, not ORIGINATED
from there... for ORIGINATED in AS300 I believe you would do
_300$
The other one is
> ^300 200$ = routes from AS 300 and 200 or 200 and 300
I believe you also have this one incorrectly interpreted. I believe it
actually means that the PATH MUST BE 300 200 in exactly that order. For
200 300 you would need ^200 300$. I believe it is a literal expresion.
If I am wrong I will be corrected soon enough.
Also, I would be careful with your interpretation of forward or
backwards paths... Let's say we stay on the same ballpark and use common
terminology. I prefer the term ORIGINATE and TRANSIT and CONNECTED as
descriptive terms in an as-path. We all agree that the origin is at the
righ hand side of the string and the connected AS is always on the left
hand side of the string... etc. etc. :-))
