enable ospf export

enable ospf export [bgp | direct | direct-inter-vr | e-bgp | i-bgp | rip | static | isis | isis-level-1 | isis-level-1-external | isis-level-2 | isis-level-2-external | host-mobility] [cost cost type [ase-type-1 | ase-type-2] {tag number} | policy-map]

Description

Enables redistribution of routes to OSPF.

Syntax Description


bgp	Specifies BGP routes.
direct	Specifies direct routes.
direct-inter-vr	Specifies Inter-VR leaked direct routes.
e-bgp	Specifies E-BGP routes.
i-bgp	Specifies I-BGP routes.
rip	Specifies RIP routes.
static	Specifies static routes.
isis	Specifies IS-IS routes.
isis-level-1	Specifies ISIS Level 1 routes.
isis-level-1-external	Specifies ISIS Level 1 External routes.
isis-level-2	Specifies ISIS Level 2 routes.
isis-level-2-external	Specifies ISIS Level 2 External routes.
host-mobility	Specifies host-mobility 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.

Default

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

Usage Guidelines

After OSPF export 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, IS-IS, 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

The following example shows all route types that can be configured with this command:

# enable ospf export 
  <route_type>    OSPF export route type
    "bgp"                    "direct"                “direct-inter-vr”
    "e-bgp"                  "host-mobility"         "i-bgp"
    "isis"                   "isis-level-1"          "isis-level-1-external"
    "isis-level-2"           "isis-level-2-external" "rip"
    "static"
