Configuring minimum SPBM and IS-IS parameters using auto-nni command

About this task

The auto-nni command provides a quick and simple way to configure the IS-IS interface. You can use the auto-nni command instead of the following existing IS-IS commands on the physical (port) interface:

• isis

• isis spbm instance

• isis enable

The existing commands are still available and you have the option to use the new command or the three existing commands. If you need to modify any of the default parameters under isis or isis spbm instance , use isis and isis spbm instance constructs even if you created the interface with the auto-nni command.

1. Enter Global Configuration mode:

   enable

   configure terminal

2. Enable SPBM globally:

   spbm

3. Enter IS-IS Router Configuration mode:

   router isis

4. Create the SPBM instance (only one SPBM instance is supported):

   spbm <1–100>

5. Add the SPBM B-VLAN to the SPBM instance:

   spbm <1–100> b-vid {<vlan-id [-vlan-id][,...]} [primary <1-4059>]

6. Configure the system nickname (2.5 bytes in the format <x.xx.xx>):

   spbm <1–100> nick-name <x.xx.xx>

   

   Note

   Although it is not strictly required for SPBM operation, you should change the IS-IS system ID from the default B-MAC value to a recognizable address to easily identify a switch (Log on to IS-IS Router configuration mode and use the system-id <xxxx.xxxx.xxxx> command). This helps to recognize source and destination addresses for troubleshooting purposes.

7. Configure an IS-IS manual area (1-13 bytes in the format <xx.xxxx.xxxx...xxxx>. Only one manual area is supported.):

   manual-area <xx.xxxx.xxxx...xxxx>

8. Exit IS-IS Router Configuration mode to Global Configuration mode:

   exit

9. Create the SPBM backbone VLAN (B-VLAN):

   vlan create <2-4059> type spbm-bvlan

10. Enter Interface Configuration mode, by specifying the ports or MLTs that are going to link to the SPBM network:

    interface {GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}| mlt <1–512> }

11. Configure an IS-IS interface on the selected ports.

    auto-nni

12. Enable interface.
13. Exit Interface Configuration mode:

    exit

14. Enable IS-IS globally:

    router isis enable

15. Display the SPBM configurations:

    show isis spbm

16. Display the global IS-IS configuration:

    show isis

17. Display the interface IS-IS configuration:

    show isis interface

Example

Switch(config-isis)# exit

Switch(config)# interface GigabitEthernet 1/21

Switch(config-if)# auto-nni

Switch(config-if)# exit

Switch(config)# vlan create 10 type spbm-vlan

Switch(config)# vlan create 20 type spbm-vlan

Switch(config)# router isis enable
