support for the Enhanced Layer 2 Software (ELS) configuration style, you can
configure spanning tree parameters globally on all spanning tree interfaces.

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.
