Using Cisco ANA PathTracer for Layer 3 VPN
Cisco ANA Path Tracer uses VRF routing and label switching information to trace the path from one VRF interface to another. If you choose a start and endpoint from the
For Layer 3 path information, Cisco ANA uses VRF routing and label switching information to trace the path from one VRF interface to another. Layer 3 Cisco ANA PathTracer information is displayed in the Cisco ANA PathTracer window when the path goes over connections and ends in VRFs.
To view Layer 3 path information, choose the Layer 3 tab and choose Show All from the View menu. The path information is displayed in the active tab.
Note Selecting a device or link on the map automatically highlights the related parameters in the table.
