configure ospf add vlan area
In either case, LDP must be configured to advertise label mappings for direct routing interfaces.
In some configurations, you may want to enable loopback mode on the VLAN to which the tunnel
endpoint IP address is assigned. One situation where loopback mode may be useful is when multiple
physical interfaces, associated with different VLANs, are connected to the MPLS backbone. In this case,
use of loopback-mode can provide redundancy by enabling TLS traffic to continue even when the
physical interfaces associated with the tunnel endpoint IP address VLAN fail.
Example
The following command enables OSPF on a VLAN named accounting:
configure ospf add vlan accounting area 0.0.0.1
