vrBrTbStpBridgeForwardDelay
Virtual Router Br Tb Stp Bridge Forward Delay
This attribute specifies how fast a bridge port changes its STP state while progressing towards the forwarding state. It is also used as agingTime to age dynamic entries in the forwarding table once a topology change is detected. This attribute is used by all the bridges participating in the spanning tree protocol, when this bridge is the root bridge. The following relationship is enforced as required by the IEEE 802.1d standards document. 2 *(bridgeForwardDelay -1.0sconds) >= bridgeMaxAge.
