packet matches an LFIB entry comprising the explicit null label, the penultimate hop replaces the value of
the top label with value 0, and forwards the packet to the egress node. The egress node gets the TC
information, pops the label of the packet, and forwards the packet.

Enabling MPLS

You must enable MPLS on all interfaces related to MPLS forwarding.
Before you enable MPLS, complete the following tasks:
Configure link layer protocols to ensure connectivity at the link layer.
•
Configure IP addresses for interfaces to ensure IP connectivity between neighboring
•
nodes.Configure static routes or an IGP protocol to ensure IP connectivity among LSRs.To enable
MPLS:
Step
1. Enter system view.
2. Configure an LSR ID for the local
node.
3. Enter the view of the interface
that needs to perform MPLS
forwarding.
4. Enable MPLS for the interface.

Remarks
N/A
By default, no LSR ID is configured.
An LSR ID must be unique in an MPLS
network and in IP address format. HP
recommends that you use the IP
address of a loopback interface as
an LSR ID.
N/A
By default, MPLS is disabled on an
interface.
