Redistributing External Routes

You can configure this router to import external routing information from

other routing protocols into the autonomous system.

Command Usage

• This router supports redistribution for both RIP and static routes.

• When you redistribute external routes into an OSPF autonomous

system (AS), the router automatically becomes an autonomous system

boundary router (ASBR).

• However, if the router has been manually configured as an ASBR via

the General Configuration screen, but redistribution is not enabled, the

router will only generate a “default” external route into the AS if it has

been configured to “always” advertise a default route even if an

external route does not actually exist (page 3-287).

• Metric type specifies the way to advertise routes to destinations outside

the autonomous system (AS) via External LSAs. Specify Type 1 to add

the internal cost metric 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. Specify Type 2 to only advertise external route metric.

• The metric value specified for redistributed routes supersedes the

Default External Metric specified in the OSPF / General

Configuration screen (page 3-287).

Command Attributes

• Redistribute Protocol – Specifies the external routing protocol type

for which routing information is to be redistributed into the local
