MPLS PE, P connectivity for MPLS transport, MPLS VPN, MPLS TEapplications

ApplicationsApplications

MPLS LSP Ping (ICMP) for connectivity checks

MPLS LSP Traceroute for hop-by-hop fault localization

MPLS LSP Traceroute for path tracing

SolutionSolution

Detect MPLS traffic black holes or misrouting

Isolate MPLS faults

MPLS AToM Virtual CircuitConnection Verification ( VCCV)

Draft-ietf-pwe3-vccv-xx.txtIETF StandardsIETF Standards

Layer 2 transport over MPLS

FRoMPLS, ATMoMPLS, EoMPLSApplicationsApplications

AToM VCCV allows sending control packets in band of an AToMpseudowire. Two components:

Signaled component to communicate VCCV capabilities as part

of VC label

Switching component to cause the AToM VC payload to be treated as acontrol packet

Type 1: uses Protocol ID of AToM Control word

Type 2: use MPLS router alert label

SolutionSolution

Ability to provide end-to-end fault detection and diagnostics for anemulated pseudowire service

One tunnel can serve many pseudowires.

MPLS LSP ping is sufficient to monitor the PSN tunnel (PE-PEconnectivity), but not VCs inside of tunnel
