On MX Series routers and EX Series and QFX 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.

NOTE: This procedure uses Junos OS for EX Series switches with support for
the Enhanced Layer 2 Software (ELS) configuration style. For ELS details,
see Getting Started with Enhanced Layer 2 Software.
On EX Series switches running Rapid Spanning Tree Protocol (RSTP) (the default) or
VLAN Spanning Tree Protocol (VSTP), you can force the original IEEE 802.1D Spanning
Tree Protocol (STP) version to run in place of RSTP or VSTP. Configure the force-version
stp statement for compatibility with older bridges that do not support RSTP or VSTP.
