redistribute
This command redistributes external routing information from other
routing protocols and static routes into an autonomous system. Use the no
form to disable this feature or to restore the default settings.

[ tag ]
connected - Imports all currently connected entries.
rip - Imports entries learned through the Routing Information
Protocol.
static - Static routes will be imported into this Autonomous
System.
metric-value - Metric assigned to all external routes for the
specified protocol. (Range: 0-16777214: Default: 10)
type-value
1 - Type 1 external route
2 - Type 2 external route (default) - Routers do not add internal
route metric to external route metric.
tag-value - A tag placed in the AS-external LSA to identify a specific
external routing domain, or to pass additional information between
routers. (Range: 0-4294967295)

◆
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). If the redistribute command is used in
conjunction with the default-information originate command to
generate a “default” external route into the AS, the metric value
specified in this command supersedes the metric specified in the
default-information originate command.
◆
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
