Randy Bush wrote: More or less. Technically, unless sender-side loop detection is used, the routers in 1,2 and 3 will receive the announcement, but discard it because it contains the local AS. However, the path will not be one of the candidates for route selection, so it will probably not appear in the output of a query for the prefix, which amounts to much the same.Thus, to stop its announcement from being propagated by ASes 1, 2, and 3, an AS (say AS12654) might announce one of its prefixes with an AS-path of 12654 {1,2,3}.
