â—† If the network addresses within an area are assigned in a contiguous manner,
the ABRs can advertise a summary route that covers all of the individual
networks within the area that fall into the specified range using a single area
range command.
â—† If routes are set to be advertised by this command, the router will issue a Type 3
summary LSA for each address range specified by this command.
â—† This router supports up 64 summary routes for area ranges.
Example
This example creates a summary address for all area routes in the range of 73::/8, or
all IPv6 address that start with the first byte 73 (hexadecimal).
Console(config-router)#area 1 range 73::/8 advertise
Console(config-router)#
default-metric This command sets the default metric for external routes imported from other
protocols. Use the no form to remove the default metric for the supported protocol
types.

metric-value – Metric assigned to all external routes imported from other
protocols. (Range: 0-16777214)

Command Usage
â—† The default metric must be used to resolve the problem of redistributing
external routes from other protocols that use incompatible metrics.
â—† This command does not override the metric value set by the redistribute
command. When a metric value has not been configured by the redistribute
command, the default-metric command sets the metric value to be used for
all imported external routes.
Example
Console(config-router)#default-metric 100
Console(config-router)#
