RP/0/RSP0/CPU0:router(config-l2vpn-bg)#
Creates a bridge group so that it can contain bridge domains and then assigns network interfaces to the bridge domain.
Step 4 bridge-domain bridge-domain name
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg)# bridge-domain abc
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)#
Establishes a bridge domain and enters L2VPN bridge group bridge domain configuration mode.
Step 5 (Optional) interface type interface_id
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)# interface gigabitEthernet 0/2/0/1
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-ac)#
Enters the interface configuration mode of the specified interface and adds this interface as the bridge domain member
interface.
Note Run this step if you want to configure the MAC address limit only for a specific interface. The further steps
show the router prompt displayed when you have skipped this step to configure the MAC address limit at
the bridge domain level.
Step 6
mac
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd)# mac
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-mac)#
Enters L2VPN bridge group bridge domain MAC configuration mode.
Step 7
limit
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-mac)# limit
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-mac-limit)#
Sets the MAC address limit for action, maximum, and notification and enters L2VPN bridge group bridge domain
MAC limit configuration mode.
Step 8 maximum { value }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-mac-limit)# maximum 5000
Configures the specified action when the number of MAC addresses learned on a bridge is reached.
Step 9
action { flood | no-flood | shutdown }
