VPLS STP Commands
stp
Syntax stp
Context config>service>vpls
config>service>vpls>sap
config>template>vpls-template
Description This command enables the context to configure the Spanning Tree Protocol (STP) parameters.
Alcatel-Lucent’s STP is simply the Spanning Tree Protocol (STP) with a few modifications to better
suit the operational characteristics of VPLS services. The most evident change is to the root bridge
election. Since the core network operating between Alcatel-Lucent’s service routers should not be
blocked, the root path is calculated from the core perspective.
auto-edge
Syntax auto-edge
no auto-edge
Context config>service>vpls>sap>stp
config>service>vpls>spoke-sdp>stp
Description This command configures automatic detection of the edge port characteristics of the SAP or spoke
SDP.
The no form of this command returns the auto-detection setting to the default value.
