Configuring BPDU Protection on All Edge Ports
On ACX Series routers, MX Series routers, and EX Series switches, 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 (STP Type) (mstp | rstp | vstp) bpdu-block-on-edge
2.
Verify BPDU protection for edge ports:
[edit]
protocols (STP Type) {
(mstp | rstp | vstp) {
bpdu-block-on-edge;
}
}
