Provider Bridging Commands
This chapter describes the Provider Bridging (PB) commands.
IEEE 802.1ad standardizes the architecture and bridged protocols to allow Ethernet frames with multiple VLAN tags. Packets through a provider network are doubly tagged with both an:
• Inner (C-VLAN) tag which is the customer network VLAN identifier
• Outer (S-VLAN) tag which is the service provider network VLAN identifier
• dotad
bridge protocol provider-mstp
Use this command to create a provider multiple spanning-tree protocol (MSTP) bridge. MSTP bridges can have different spanning-tree topologies for different VLANs inside a region of similar MSTP bridges.
Using this command creates an instance of the spanning tree, and associates the VLANs specified with that instance. A bridge created by this command forms its own separate region.
The multiple spanning tree protocol, like the rapid spanning tree protocol, provides rapid reconfiguration features, while providing load-balancing capability.
Command Syntax
bridge <1-32> protocol provider-mstp (edge|)
Parameters
<1-32>
Bridge identifier.
edge
Configure as an edge bridge.
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 2 protocol provider-mstp edge
 
bridge protocol provider-rstp
Use this command to add an IEEE 802.1D-2004 Rapid Spanning Tree Protocol (RSTP) bridge.
After creating a bridge instance, add interfaces to the bridge using the bridge-group command. Bring the bridge instance into operation with the no shutdown command in interface mode.
Command Syntax
bridge <1-32> protocol provider-rstp (edge|)
Parameters
<1-32>
Bridge identifier.
edge
Configure as an edge bridge.
Command Mode
Configure mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
#configure terminal
(config)#bridge 2 protocol provider-rstp edge
 
 
 
 
 
 
cvlan registration table
Use this command to create a customer VLAN (CVLAN) registration table that maps between CVLANs and service provider VLANs (SVLANs).
