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:
Include the bpdu-timeout-action statement with either the block or log option for the spanning-tree protocol interface.
For the STP or RSTP instance on a physical interface:
[edit]For all MSTP instances on a physical interface:
[edit]For all VSTP instances on a physical interface configured at the global level or a the VLAN level:
[edit]protocols {vstp {interface interface-name {bpdu-timeout-action (log | block);}vlan vlan-id {interface interface-name {bpdu-timeout-action (log | block);}}}}
- To display the spanning-tree protocol loop protection characteristics on an interface, use the show spanning-tree interface operational command.
