3 Configuring the Switch

AS Boundary Router 24 – Allows this router to exchange routing information with boundary routers

in other autonomous systems to

which it may be attached. If aAS 1 ASBR router is enabled as an ASBR,

then every other router in the autonomous system can learn

about external routes from this device. (Default: Disabled)

ASBR

AS 2

Rfc1583 Compatible – If one or more routers in a routing domain are using OSPF Version 1, this router should use RFC 1583 (OSPFv1) compatibility mode to ensure that all routers are using the same RFC for calculating summary route costs.

Enable this field to force the router to calculate summary route costs using RFC 1583. (Default: Disabled)

SPF Hold Time (seconds) – The hold time between making two consecutive shortest path first (SPF) calculations. (Range: 0-65535; Default: 10)

Area Numbers23 – The number of OSPF areas configured on this router.

Default Route Information –

Originate Default Route24 – Generates a default external route into an autonomous system. Note that the AS Boundary Router field must be enabled, and the Advertise Default Route field properly configured. (Default: Disabled)

Advertise Default Route24 – The router can advertise a default external route into the autonomous system (AS). (Options: NotAlways, Always; Default: NotAlways)

Always – The router will advertise itself as a default external route for the AS, even if a default external route does not actually exist.

NotAlways – It can only advertise a default external route into the AS if it has been configured to import external routes via RIP or static configuration, and such a route is known. (See “Redistributing External Routes” on page 3-253.)

External Metric Type24 – The external link type used to advertise the default route. Type 1 route advertisements add the internal cost to the external route metric. Type 2 routes do not add the internal cost metric. When comparing Type 2 routes, the internal cost is only used as a tie-breaker if several Type 2 routes have the same cost. (Default: Type 2)

Default External Metric24 – The Metric assigned to the default route. (Range: 1-65535; Default: 10)

24. CLI - These are configured with the default-information originate command (page 4-267).
