show mpls label Field Definitions

Field Definition
Advertised Label Advertised Label is the label advertised to other routers.
Destination Mapping Destination Mapping displays the destination IP address and mask.
LSP Flags LSP Flags lists the flags for each label, which are described in the key at the bottom of the display.
Peer Label The peer label that replaces the received label of incoming packets during a label swap on a transit LSP. The peer label appears only for transit LSPs.
NHop Type

NHop Type helps define the handling of a packet arriving with the specified advertised label. Possible values are:

IP—The label on the packet is swapped and the packet forwarded to the IP address shown in the NextHop field.locl—Indicates that the tunnel destination is local to this switch.

VLAN (Virtual LAN)—The label on the packet is stripped and is IP routed according to the Destination Mapping field.

VRF—For advertised labels, the Next Hop column contains the name of the virtual router to which packets with the given Layer 3 VPNlabel will be forwarded. For received labels, the Next Hop column displays the router ID of the BGP (Border Gateway Protocol) peer, and the Name column displays the name of the VR using this label.

VPLS—The label on the packet is stripped and forwarded according to the service configuration of the VPLS specified in the Name field.

Next Hop Displays an interface ID for the next hop router, which can be a VLAN name, VMAN name, or IP address.
Name Displays a VPLS or LSP name.
Received Label Received Label displays the label received from other routers.
Note

Note

Unsupported labels will contain no information.

History

This command was first available in ExtremeXOS 11.6.

This command was modified to display only RSVP-TE and static label information in ExtremeXOS 12.5. Additional commands were added to display LDP Layer 2 VPN and Layer 3 VPN labels.

Platform Availability

This command is available only on the platforms that support MPLS (Multiprotocol Label Switching) as described in the ExtremeXOS 22.6 Feature License Requirements document.
