Configure Remote IS-IS Global Parameters

About this task

Perform this procedure to configure remote IS-IS global parameters. SPBM uses IS-IS to discover network topology, build shortest path trees between network nodes, and communicate network information in the control plane.

Procedure

  1. In the navigation pane, expand Configuration > Fabric.
  2. Select IS-IS Remote.
  3. Select the Globals tab.
  4. Configure the remote IS-IS global parameters.
  5. Select Apply.

Globals Field Descriptions

Use the data in the following table to use the Globals tab.

Name

Description

AdminState

Specifies the global status of remote IS-IS on the switch. The default is off.

SystemId

Specifies the IS-IS system ID for the switch. Valid value is a 6–byte value in the format <xxxx.xxxx.xxxx>.

Important:

After you configure the SPBM nickname and enable remote IS-IS, if you change the system ID, you must also change the nickname. However, changing the nickname could impact the naming convention or configuration. To maintain the same nickname with a different system ID, see Job aid.

DynamicallyLearnedArea

For FAN members, specifies the remote IS-IS area that is dynamically learned from the neighbor‘s Hello PDU if the node does not have the IS-IS manual area configured.

MAOperState

Specifies the Multi-area SPB operational state:

  • Disabled – Multi-area SPB is disabled on the switch.

  • Init – the switch is initializing to function as a boundary node.

  • Designated – the switch is up and running as a designated boundary node.

  • Non-designated – the switch is up and running as a non-designated boundary node.

The default is disabled.
MAFlags

Specifies the Multi-area SPB as a boundary node to forward traffic from the UNIs to the remote-area and from the remote-area to the UNIs without requiring an established adjacency in the home area.

The default is disabled.
