Asante Technologies 40240/40480-10G - Manual (Page 742)

Command Usage
• This command is used to import routes learned from other routing protocols
into the OSPF domain, and to generate AS-external-LSAs.
• When external routes are redistributed 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 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.
Example
This example redistributes routes learned from RIP as Type 1 external routes.
Console(config-router)#redistribute rip metric-type 1
Console(config-router)#

network area
This command defines an OSPF area and the interfaces that operate within this
area. Use the no form to disable OSPF for a specified interfaces.
Syntax
[no] network ip-address netmask area area-id
• ip-address - Interfaces with addresses that fall within the network address
are added to the operational OSPF area.
• netmask - Network mask of the address range to add to the area.
• area-id - Area to which the matching interfaces are assigned. An OSPF
area identifies a group of routers that share common routing information.
(The area ID must be in the form of an IPv4 address.)
