In other words, inter-area routes are calculated by examining summary-LSAs. If
the router is an ABR and has an active backbone connection, only backbone
summary-LSAs are examined. Otherwise (when either the router is not an ABR
or it has no active backbone connection), the router should consider summary-
LSAs from all actively attached areas.
This ensures that the summary-LSAs originated by area border routers
advertise only intra-area routes into the backbone if the router has an active
backbone connection, and advertises both intra-area and inter-area routes into
the other areas. Otherwise, the router only advertises intra-area routes into
non-backbone areas.
Example
Console(config-router)#abr-type ibm
Console(config-router)#
max-current-dd This command sets the maximum number of neighbors with which the switch can

â—† This limit applies separately to the number of neighbors to which DD packets
