Ability to Enable/Disable Reflection Bridge Protocol Data Unit (BPDU) Behavior in Spanning Tree Protocol (STP)

For Rapid Spanning Tree Protocol (RSTP) proposal handshake to work with CISCO switches, the switch that receives the proposal BPDU reflects back the same BPDU (all the contents) with an agreement flag set. This ensures that the other port is acknowledging the proposal that the switch has send out, so the acknowledgment BPDU contains the same contents of the other switch's proposal BPDU with the agreement bit set, instead of the proposal bit.

However, this behavior when used with EOS upstream bridges receiving the agreement BPDU (whose MAC OUI is different than 00:01:F4, 00:11:88, 00:1F:45, 20:B3:99) causes the switch to believe it is being sent its own BPDU, thus causing a multisource event during a topology change.

This feature allows you turn off the BPDU reflection behavior to avoid this problem.
