DETAILED STEPS
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Enters the Global Configuration mode.
Step 2 l2vpn
Example:
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 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 interface type interface-path-id. subinterface
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-ac)# interface GigabitEthernet0/5/0/1.15
Adds an interface to a bridge domain that allows packets to be forwarded and received from other interfaces that are part
of the same bridge domain. The interface now becomes an attachment circuit on this bridge domain.
