There are two manifestations of this problem. The first, discovered by DennisFerguson, occurs when an aggregated forwarding address is in use. In this case, the desirability of the forwarding address can change for the worse as a packet crosses an area aggregation boundary on the way to the forwarding address, which in turn can cause the preference of AS-external-LSAs to change, resulting in a routing loop.<\/em><\/p>\n

    There are two manifestations of this problem. The first, discovered by DennisFerguson, occurs when an aggregated forwarding address is in use. In this case, the desirability of the forwarding address can change for the worse as a packet crosses an area aggregation boundary on the way to the forwarding address, which in turn can cause the preference of AS-external-LSAs to change, resulting in a routing loop.<\/em><\/p>\n
