Disabling a Virtual Forwarding Instance
Perform this task to disable a VFI. When a VFI is disabled, all the previously established pseudowires that
are associated with the VFI are disconnected. LDP advertisements are sent to withdraw the MAC addresses
that are associated with the VFI. However, you can still attach or detach attachment circuits with a VFI after
a shutdown.
