• isis redistribute ospf [enable] [metric <0-65535>] [metric-type <external | internal>] [route-map WORD<0-64 ] [subnets <allow | suppress>] [tag <1-4294967295>]

• no isis redistribute ospf [enable] [metric] [metric-type] [route-map] [subnets] [tag]

Command Parameters

enable

Enables route redistribution.

metric <0-65535>

Configures the metric (cost) to apply to redistributed routes. The default is 1.

metric-type <external | internal>

Configures the type of route to import into the protocol. The default is internal.

routemap WORD<0-64>

Configures the route policy to apply to redistributed routes. Specifies a name.

subnets <allow | suppress>

Indicates whether the subnets are advertised individually or aggregated to their classful subnet. Choose allow to advertise the subnets individually with the learned or configured mask of the subnet. The default is allow.

tag <1-4294967295>

Apply a tag to routes that OSPF redistribute to IS-IS. You can then configure router filtering to prevent tagged IS-IS routes from being redistributed back to OSPF.

Default

By default, redistribution is disabled.

Command Mode

VRF Router Configuration

Usage Guidelines

Caution

To use IS-IS Route Tagging on GRT IS-IS routes, you must also configure the metric-type as external. If you want to use IS-IS tags on GRT as internal routes, all Fabric nodes must be above a minimum software version. Any switch in the SPB Fabric that runs earlier software versions triggers an exception if you use metric type internal. To ensure this does not occur, if you attempt to configure a tag and the metric-type is not external, the switch reminds you to upgrade the software on all devices. You must ensure all devices in the network run the minimum required software.
