6.11.10 Configuring Route Summarization In OSPF Area
This feature causes a single summary route to be advertised to other areas by an ABR. In OSPF, an

assigned in a way such that they are contiguous, you can configure the ABR to advertise a summary
route that covers all the individual networks within the area that fall into the specified range.
To specify an address range, use the following command in router configuration mode:
