Configuring BPDU Protection on All Edge Ports

On MX Series routers, you can configure BPDU protection to ignore BPDU received on interfaces where none should be expected. If a BPDU is received on a blocked interface, the interface is disabled and stops forwarding frames. By default, all BPDUs are accepted and processed on all interfaces.

To configure BPDU protection for all edge ports for a particular spanning-tree protocol::

1. Enable edge port blocking for a particular spanning-tree protocol:
   
   

   [edit]
user@host# set protocols (mstp | rstp | vstp) bpdu-block-on-edge

2. Verify BPDU protection for edge ports.

   [edit]protocols {(mstp | rstp | vstp) {bpdu-block-on-edge;}}
