Router configuration Use this command with ABRs to summarize the intra-area routes. This command is used to specify the summarized route for area 0 or for a non-zero area. Multiple area router configuration commands specifying the range option can be configured. Thus, OSPF can summarize addresses for many different sets of address ranges.
