Configure Required SPBM and IS-IS Parameters

About this task

Perform this procedure to configure the minimum required SPBM and IS-IS parameters to enable SPBM to operate on the switch. SPBM uses the Intermediate-System-to-Intermediate-System (IS-IS) link state routing protocol to provide a loop free Ethernet topology that creates a shortest path topology from every node to every other node in the network based on node MAC addresses.

Procedure

  1. Configure SBPM B-VLANs:
    Note

    Note

    Always configure two B-VLANs in the core to enable load distribution over both B-VLANs.

    1. In the navigation pane, expand Configuration > VLAN.
    2. Select VLANs.
    3. Select the Basic tab.
    4. Select Insert.
    5. In type, select spbm-bvlan.
    6. Select Insert.
  2. Enable SPBM globally:
    1. In the navigation pane, expand Configuration > Fabric.
    2. Select SPBM.
    3. Select the Globals tab.
    4. In GlobalEnable, select enable to enable SPBM globally.
    5. Select Apply.
  3. Create an SPBM instance:
    Note

    Note

    Only one SBPM instance is supported.

    1. In the navigation pane, expand Configuration > Fabric.
    2. Select SPBM.
    3. Select the SPBM tab.
    4. Select Insert to create an SPBM instance.
    5. In Id, specify the SPBM instance ID.
    6. In NodeNickName, specify the node nickname (valid value is 2.5 bytes in the format <x.xx.xx>).
    7. In Vlans, specify the IDs of the SPBM B-VLANs to add to the SPBM instance.
    8. In PrimaryVlan, specify which of the SPBM B-VLANs specified in the previous step is the primary B-VLAN.
    9. Select Insert.
  4. Create a manual area:
    Note

    Note

    Only one manual area is supported.

    1. In the navigation pane, expand Configuration > Fabric.
    2. Select IS-IS.
    3. Select the Manual Area tab.
    4. Select Insert.
    5. Specify the Manual Area address (a valid value is 1–13 bytes in the format <xx.xxxx.xxxx...xxxx>).
    6. Select Insert.
  5. Update the default IS-IS system ID to a recognizable address:
    1. In the navigation pane, expand Configuration > Fabric.
    2. Select IS-IS.
    3. Select the Globals tab.
    4. In SystemId, update the default BMAC value to a recognizable address.
      Note

      Note

      Although it is not strictly required for SPBM operation, you must change the IS-IS system ID from the default BMAC value to a recognizable address to easily identify a switch. This helps to recognize the source and destination addresses for troubleshooting purposes.

    5. In AdminState, select on.
    6. Select Apply.
  6. Create an IS-IS circuit and enable SPBM on the circuit:
    1. In the navigation pane, expand Configuration > Fabric.
    2. Select IS-IS.
    3. Select the Interfaces tab.
    4. Select Insert to create an IS-IS circuit.
    5. In IfIndex, specify the port or MLT on which to create the IS-IS circuit.
    6. Select Insert.
    7. Select the newly created IS-IS circuit entry, and select SPBM.
    8. In the Interfaces SPBM tab, select Insert.
    9. In State, select enable.
    10. Select Insert to enable the SPBM instance on the IS-IS circuit.
    11. Navigate back to the Interfaces tab.
    12. In AdminState for the IS-IS circuit entry, select on to enable the IS-IS circuit.
    13. Select Apply.

Job aid

Important

Important

After you have configured the SPBM nickname and enabled IS-IS. To maintain the same nickname with a different system ID, perform the following steps:

  1. Disable IS-IS.

  2. Change the system ID.

  3. Change the nickname to a temporary one.

  4. Enable IS-IS.

  5. Wait up to 20 minutes for the LSPs with the original system ID to age out.

    Note

    Note

    To check the age out time, use the show isis lsdb sysid <original-sys-id> command on any of the other SPB nodes in the network. When there is no output from this command, proceed to the next step. The time left (in seconds) for the LSPs to age out is shown under the column LIFETIME.

  6. Disable IS-IS.

  7. Change the nickname to the original nickname.

  8. Enable IS-IS.
