Traffic Engineering LSPs Tab
The Traffic Engineering LSPs tab describes the MPLS traffic engineering Label Switched Paths (LSPs)
provisioned on the switch entity. MPLS traffic engineering LSP, an extension to MPLS TE, provides
flexibility when configuring LSP attributes for MPLS TE tunnels. Traffic engineering LSP properties
include:
• LSP Type—The LSP role: head, tail, middle, all, remote
• Source Address—The source IP address.
• In Interface—The input interface.
• In label—The input label.
• Out Interface—The output interface.
• Out Label—The output label.
• Destination Address—The destination IP address.
• LSP Name—The LSP name.
• LSP ID—The LSP identification.
• Average Bandwidth—The average tunnel bandwidth.
• Burst—The tunnel burst rate, in kb/s.
• Peak—The tunnel peak rate, in kb/s.
• Sending Alarms—Indicates whether or not the entity is sending alarms.
VRF Table Tab
The VRF Table tab describes the MPLS paths that terminate locally at a VRF. The following information
is displayed:
• Incoming Label—The details of the incoming VRF label.
• Action—The action that will be invoked: push, pop, swap, or untagged.
• VRF—The VRF name as a hyperlink; displays the VRF properties.
• IP Destination—The destination IP address.
• Destination Mask—The destination IP subnet mask.
• Next Hop—The next hop.
• Out Interface—The out interface.
• Sending Alarms—This option is currently unavailable.
LDP Neighbors Tab
The LDP Neighbors tab provides details of all MPLS interface peers that use the Label Distribution
Protocol (LDP). LDP enables neighboring provider (P) or PE routers acting as label switch routers
(LSRs) in an MPLS-aware network to exchange label prefix binding information, which is required for
forwarding traffic. The LSRs discover potential peers in the network with which they can establish LDP
sessions in order to negotiate and exchange the labels (addresses) to be used for forwarding packets.
