11)If both paths are external, prefer the currently active path to minimize route-flapping. This rule is not used if:
path-selection external-router-id is configured.
Both peers have the same router ID.
Either peer is a confederation peer.
Neither path is the current active path.
12)Prefer the path from the peer with the lowest router ID. For any path with an originator ID attribute, substitute the originator ID for the router ID during router ID comparison.
