Deployment Guide

You can determine if an ASBR is in a directly connected area (or not) by the ags. For ASBRs in a directly
connected area, E ags are set. In the following example, router 1.1.1.1 is in a directly connected area since the Flag
is E/-/-/. For remote ASBRs, the E ag is clear (-/-/-/).
