Route Re-Distribution
Re-Distributing Routes into OSPF
Enable or disable the exporting of BGP, RIP, static, and direct (interface) routes to OSPF using the
following commands:
enable ospf export [bgp | direct | e-bgp | i-bgp | rip | static] [cost <cost> type
[ase-type-1 | ase-type-2] {tag <number>} | <policy-map>]
disable ospf export [bgp | direct | e-bgp | i-bgp | rip | static]
These commands enable or disable the exporting of RIP, static, and direct routes by way of LSA to other
OSPF routers as AS-external type 1 or type 2 routes. The default setting is disabled.
The cost metric is inserted for all BGP, RIP, static, and direct routes injected into OSPF. If the cost metric
is set to 0, the cost is inserted from the route. For example, in the case of BGP export, the cost equals the
MED or the path length. The tag value is used only by special routing applications. Use 0 if you do not
have specific requirements for using a tag. The tag value in this instance has no relationship with
802.1Q VLAN tagging.
The same cost, type, and tag values can be inserted for all the export routes, or policies can be used for
selective insertion. When a policy is associated with the export command, the policy is applied on every
exported route. The exported routes can also be filtered using policies.
Verify the configuration using the command:
show ospf
Re-Distributing Routes into RIP
Enable or disable the exporting of static, direct, BGP-learned, and OSPF-learned routes into the RIP
domain using the following commands:
enable rip export [bgp | direct | e-bgp | i-bgp | ospf | ospf-extern1 | ospf-extern2 |
ospf-inter | ospf-intra | static] [cost <number> {tag <number>} | policy
<policy-name>]
disable rip export [bgp | direct | e-bgp | i-bgp | ospf | ospf-extern1 | ospf-extern2
| ospf-inter | ospf-intra | static]
These commands enable or disable the exporting of static, direct, and OSPF-learned routes into the RIP
domain. You can choose which types of OSPF routes are injected, or you can simply choose , which
ospf
will inject all learned OSPF routes regardless of type. The default setting is disabled.

OSPF Timers and Authentication

Configuring OSPF timers and authentication on a per-area basis is a shorthand for applying the timers
and authentication to each VLAN in the area at the time of configuration. If you add more VLANs to
the area, you must configure the timers and authentication for the new VLANs explicitly. Use the
command:
configure ospf vlan [<vlan-name> | all] timer <retransmit-interval>
<transit-delay> <hello-interval> <dead-interval> {<wait-timer-interval>}
