Thanks for the clarification Jason. I do understand it better now: Just like
a normal route-map, the clause must make a match (or have no match
statement, in other words a "match any" type behavior) in order to execute
the continue. If there is a match statement, but nothing is matched, the
continue is not executed.
In this case, R6 did prepend the AS numbers 65123 amd 65234 so it looks like
continue doesn't work. I've only been working with Cisco gear for about a
year, with some CCNA/CCNP studying before that but I never came across a
command that was there but didn't work.
I'm sure some more experienced vets have seen it though :)
