Configuring multicast on the switch

This procedure shows how to configure PIM and IGMP Snooping in an SMLT environment. The configuration steps show how to enable multicast, and then configure the usual PIM and IGMP Snooping related VLANs and global attributes. It includes steps to configure the following:

  • Setting the boot config flag

  • Configuring the vIST peer

  • Enabling Simplified vIST

Before you begin

SPBM must not be enabled on the vIST peers or any router participating in the PIM network.

Procedure

  1. In the navigation pane, expand the Configuration > Edit > Chassis folders.
  2. Click the Boot Config tab.
  3. Clear the EnableSpbmConfigMode to disable the boot flag.

    The system responds with these messages:

    Warning: Please save the configuration and reboot the switch for this to take effect.

    Warning: Please carefully save your configuration file before rebooting the switch. Saving configuration file when spbm-config-mode is changed to disable, removes SPBM configurations from the configuration file.

  4. Click Apply.
  5. Save the configuration, and then reboot the switch.
