Or you could summarize the networks you are receiving from AS1 using the
aggregate-address summary-only command. The aggregate would be advertised
as being originated by AS2; and with the summary-only keyword, only the
aggregate would be announced.

"set as-path" only allows AS prepends, no deletions. RFC 1771 does not
mention anything about AS path deletions, but I suspect it's frowned upon.
You might be stuck with the confederation solution.
