l2 vfi
To create a virtual forwarding infrastructure (VFI) and to enter manual VFI configuration mode, use the
l2 vfi command in global configuration mode. A VFI is a logical switching entity used to implement
hierarchical virtual private LAN service (H-VPLS) over a multiprotocol label switching (MPLS)
backbone. All interfaces attached to the VFI can participate in the switching. To delete the VFI, use the
no form of this command.

Command History
Usage Guidelines Entering the l2 vfi vfi-name manual command enables the VFI configuration mode. These configuration
commands are available:
•
default : sets the command to the default states.
•
exit : exits VFI configuration mode and returns to global configuration mode.
• no : negates a command or set its defaults.
•
vpn id vpn-number : specifies the virtual private network (VPN) ID of the VPLS configured by the
VFI. For more information, see the vpn id command.
When you enter a vpn id vpn-number, these additional VFI configuration commands are available:
•
neighbor remote-peer-IP-address encapsulation mpls : configures the IP address of the remote
peer, which is to become a member of the VPLS configured by the VFI, and sets the MPLS
encapsulation type.
•
shutdown : shuts down the VFI interface.
The switch supports only one connection per VFI, so you can configure only one neighbor in a VFI. To
complete the connection, you attach a VLAN or Ethernet interface to the VFI by using the
xconnect
interface configuration command. The switch supports multiple Ethernet interfaces or a single VLAN in
a VFI. It does not support switching a VLAN and physical interfaces through the same VFI.
The switch supports a total of 26 VRFs and VPNs.
vfi-name Name assigned to the VFI.
