Chapter 5 Viewing MPLS Logical Inventory
Viewing MPLS TE Tunnel Information
•Tunnel ID—The identifier that, along with the router IP addresses of the two tunnel edges, identifies the PWE3 tunnel.
•Peer Router IP—The IP of the peer tunnel edge, which is used as the MPLS router ID.
•Signaling Protocol—The protocol used by MPLS to build the tunnel, for example, LDP or TDP.
•Sending Alarms—This option is currently unavailable.
For information on viewing Links in MPLS TE tunnels see Chapter 8, “Impact Analysis in MPLS Networks” and Chapter 9, “Using Cisco ANA PathTracer in MPLS Networks.”
Viewing MPLS TE Tunnel Information
The Traffic Engineering Tunnels branch displays specific TE tunnel information. The name of the table is displayed at the top of the Properties window in the title bar. The following information is displayed in the Tunnel Edges table:
•Name—The name of the TE tunnel (in Cisco devices it is the interface name).
•Tunnel Destination—The IP address of the device in which the tunnel ends.
•Administrative Status—The administrative state of the tunnel, namely, up or down.
•Operational Status—The operational state of the tunnel, namely, up or down.
•Outgoing Label—The TE tunnel’s MPLS label distinguishing the LSP selection in the next device.
•Description—A textual description of the tunnel.
•Outgoing Interface—The interface through which the tunnel exits the device.
•Bandwidth (Kbps)—Bandwidth specification for this tunnel.
•Setup Priority—The tunnel’s priority upon path setup.
•Hold Priority—The tunnel’s priority after path setup, when other tunnels try to remove it and claim its resources.
•Affinity—The tunnel’s preferential bits for specific links.
•Affinity Mask—Dictates which bits from the tunnel’s affinity should be compared to which bits of the link’s attribute bits.
•Auto Route—If enabled, destinations behind the tunnel are routed through the tunnel.
•Lockdown—If enabled, the tunnel cannot be rerouted.
•Path Type—The tunnel path type, either dynamic or explicit. If dynamic, the tunnel is routed along the ordinary routing decisions after taking into account the tunnel constraints such as attributes, priority, and bandwidth. If explicit, the route is explicitly mapped with the included and excluded links.
•Average Rate, Burst and Peak—Flow specification measured for this tunnel (in Kb/s).
•LSP ID—LSP identification number.
•Sending Alarms—This option is currently unavailable.
•EXP Bit—The MPLS experimental bit used for policy-based tunnel selection (PBTS) traffic. This information is available only for Cisco CRS-1 routers running Cisco IOS XR 3.6 software in MPLS or MPLS VPN networks.
