7. Below is shown a portion of the BGP Table in router X. This router has discovered three different paths to destination network 150.88.0.0/16 in AS 1605. For each path, the BGP Table shows the Next Hop address for the next BGP router along this path towards that destination network, as well as 4 Path Attributes, which are "Metric", "Local Preference", "Weight" and "AS Path".
