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 interface type interface-path-id.subinterface
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)# interface GigabitEthernet0/5/0/0.20
Assigns the matching VLAN ID and Ethertype to the interface.
Step 6 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 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.
