Configuring Loop Protection for a Spanning-Tree Instance Interface

Before you begin, you must fully configure the spanning-tree protocol, including instance interfaces. You can configure RSTP, MSTP, or VSTP at the following hierarchy levels:

  • [edit protocols]
  • [edit routing-instances routing-instance-name protocols]

To configure enhanced loop protection:

  1. Include the bpdu-timeout-action statement with either the block or alarm option for the spanning-tree protocol interface.

  2. To display the spanning-tree protocol loop protection characteristics on an interface, use the show spanning-tree interface operational command.
