mpls label mode

Use this command to configure how MPLS labels are assigned.

Syntax

mpls label mode {per-prefix | per-vrf}

no mpls label mode {per-prefix | per-vrf}

per-prefix	Specifies that MPLS allocates a unique label for each prefix route in the routing table.
per-vrf	Specifies that MPLS allocates a single label for the named VRF (default).

MPLS allocates a single label for the VRF.

A named VRF global configuration mode.

The per-prefix option is not supported when the core network is GRE.

When the MPLS label mode is set to per-vrf, all prefix routes within the routing table for the VRF context use the same label.

The “no” form of this command resets the MPLS label mode to a single label for each VRF.

This example shows how to set the MPLS label mode to per-prefix for VRF vpnA:

System(rw)->router vpnA
System(su-vpnA)->configure
System(su-vpnA-config)->mpls label mode per-prefix
System(su-vpnA-config)->

This example shows how to set the MPLS label mode so that all prefix routes within the routing table for VRF vpnA use the same label:

System(rw)->router vpnA
System(su-vpnA)->configure
System(su-vpnA-config)->mpls label mode per-VRF
System(su-vpnA-config)->
