E.7 Flushing anomalous network links advertisements

E.7 Flushing anomalous network links advertisements

Text was added indicating that a network links advertisement whose Link State ID is equal to one of the router's own IP interface addresses should be considered to be self-originated, regardless of the setting of the advertisement's Advertising Router. If the Advertising Router of such an advertisement is not equal to the router's own Router ID, the advertisement should be flushed from the routing domain using the premature aging procedure specified in Section 14.1. This case should be rare, and it indicates that the router's Router ID has changed since originating the advertisement.

Failure to flush these anomalous advertisements could lead to multiple network links advertisements having the same Link State ID. This in turn could cause the Dijkstra calculation in Section 16.1 to fail, since it would be impossible to tell which network links advertisement is valid (i.e., more recent).

This change appears in Sections 13.4 and 14.1.
