The result is that a single summary route is advertised to other areas by the ABR. Routing information is condensed at area boundaries. External to the area, a single route is advertised for each address range. The following example specifies one summary route to be advertised by the Area Border Routers to other areas for IPv6 prefix 2001:0DB8:0:1::/64 and for the Router ID 20.0.1.10.
