RSTP or VSTP Forced to Run as IEEE 802.1D STP
On MX Series routers and EX Series switches in a Layer 2 environment, you can force the configured Rapid Spanning Tree Protocol (RSTP) or VLAN Spanning Tree Protocol (VSTP) to run as the original IEEE 802.1D Spanning Tree Protocol (STP) version. Configure original IEEE_802.1D STP for compatibility with older bridges that do not support RSTP or VSTP.
Keep the following limitations in mind when RSTP or VSTP are forced to run as the original STP version:
- If you configure an instance interface as an edge port, the configuration statement is ignored.
- If you configure point-to-point link mode for an instance interface, the configuration statement is ignored.
