◆ This command is used to import routes learned from other routing
protocols into the OSPF domain, and to generate AS-external-LSAs.
◆ When you redistribute external routes into an OSPF autonomous
system (AS), the router automatically becomes an autonomous system
boundary router (ASBR).
◆ Metric type specifies the way to advertise routes to destinations outside
the AS through External LSAs. When a Type 1 LSA is received by a
router, it adds the internal cost to the external route metric. In other
words, the cost of the route from any router within the AS is equal to
the cost associated with reaching the advertising ASBR, plus the cost of
the external route. When a Type 2 LSA is received by a router, it only
uses the external route metric to determine route cost.
E XAMPLE
This example redistributes automatically connected routes as Type 1
external routes.

Area Configuration
area stub This command defines a stub area. To remove a stub, use the no form
without the optional keyword. To remove the summary attribute, use the
no form with the summary keyword.
S YNTAX
[no] area area-id stub [no-summary]
area-id - Identifies the stub area. The area ID can be in the form of
an IPv4 address or as a four octet unsigned integer ranging from
0-4294967295.
