RP/0/RSP0/CPU0:router(config)# l2vpn
Enters L2VPN configuration mode.
Step 3 bridge group bridge-group-name
Example:
RP/0/RSP0/CPU0:router(config-l2vpn)# bridge group pbb
Enters configuration mode for the named bridge group. This command creates a new bridge group or modifies the existing
bridge group if it already exists. A bridge group organizes bridge domains.
Step 4 bridge-domain domain-name
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg)# bridge-domain pbb-core
Enters configuration mode for the named bridge domain. This command creates a new bridge domain or modifies the
existing bridge domain if it already exists.
Step 5 pbb core
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)# pbb core
Configures the bridge domain as PBB core and enters the PBB core configuration submode.
This command also creates an internal port known as Customer bridge port (CBP).
All the interfaces (bridge ports) under this bridge domain are treated as the provider network ports (PNP).
Step 6 mmrp-flood-optimization
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-pbb-core)# mmrp-flood-optimization
Enables the flood optimization for PBB over VPLS feature on the core bridge.
Step 7 Use the commit or end command.
commit - Saves the configuration changes and remains within the configuration session.
end - Prompts user to take one of these actions:
• Yes - Saves configuration changes and exits the configuration session.
• No - Exits the configuration session without committing the configuration changes.
• Cancel - Remains in the configuration mode, without committing the configuration changes.
