To address the objection that there are too many subnets, routers, and multihomed hosts on the Internet submap, a map builder will add containers (location icons) to the map and label them according to their geography or purpose. Then judicious select, drag, and drop operations will place most of the icons into their appropriate “home” containers. The steps are simple:
export MAP_CUSTOMIZATION=true (NNM 5.x only)
start ovw and create a new map
open the Internet submap
turn autolayout off for this submap
turn overlay off
create containers by adding and labeling location symbols
leave routers that connect sites in the Internet submap
drag site routers into their appropriate site icons
arrange locations and routers geographically
export the customization
