enable ospf export

ExtremeWare XOS 10.1 Command Reference Guide 555

enable ospf export

[cost <cost> type [ase-type-1 | ase-type-2] {tag <number>} | <policy-map>]

Description

Enables redistribution of routes to OSPF.

Syntax Description

Default

The default tag number is 0. The default setting is disabled.

Usage Guidelines

After it is enabled, the OSPF router is considered to be an ASBR. Interface routes that correspond to the

interface that has OSPF enabled are ignored.

The cost metric is inserted for all BGP, RIP-learned, static, and direct routes injected into OSPF. If the

cost metric is set to 0, the cost is inserted from the route. 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 a policy 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 a policy.

Example

The following command enables OSPF to export BGP-related routes using LSAs to other OSPF routers:

enable ospf export bgp cost 1 ase-type-1 tag 0

bgp Specifies BGP routes.

i-bgp Specifies I-BGP routes.

direct Specifies direct routes.

e-bgp Specifies E-BGP routes.

rip Specifies RIP routes.

static Specifies static routes.

cost Specifies a cost metric.

ase-type-1 Specifies AS-external type 1 routes.

ase-type-2 Specifies AS-external type 2 routes.

number Specifies a tag value.

policy-map Specifies a policy.
