Command Manual – IPv4 Routing
H3C S7500E Series Ethernet Switches Chapter 3 OSPF Configuration Commands
3-2
This command is usable only on an ABR. Multiple contiguous networks may be
available in an area, where you can summarize them with one network on the ABR for
advertisement. The ABR advertises only the summary route to other areas.
With the undo abr-summary command used, summarized routes will be advertised.
Examples
# Summarize networks 36.42.10.0/24 and 36.42.110.0/24 in Area 1 with 36.42.0.0/16.
