mpls ip

To enable MPLS forwarding of IPv4 packets along normally routed paths for a specified interface, use
the mpls ip command in the interface configuration mode. To disable this feature, use the no form of
this command.

Usage Guidelines MPLS forwarding of IPv4 packets along normally routed paths is sometimes called dynamic label
switching. If dynamic label switching has been enabled for the platform when this command is issued
on an interface, label distribution for the interface begins with the periodic transmission of neighbor
discovery Hello messages on the interface. When the outgoing label for a destination routed through the
interface is known, packets for the destination are labeled with that outgoing label and forwarded
through the interface.
The no form of this command causes packets routed out through the interface to be sent unlabeled; this
form of the command also terminates label distribution for the interface. However, the no form of the
command does not affect the sending of labeled packets through any Label Switched Path (LSP) tunnels
that might use the interface.
