Using Cisco ANA PathTracer for Layer 3 VPN

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 right-click menu, you can open the Cisco ANA PathTracer for Layer 3 VPNs. The Cisco ANA PathTracer multipath window shows the VPN topology map. From this window, you can open the Cisco ANA PathTracer single-path window with the appropriate VPN information displayed in the Layer 2 and Layer 3 tabs.

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.

The Cisco ANA PathTracer single-path window with the Layer 3 tab is displayed. The table displays the Layer 3 VPN information on the device that has a VRF. The following Layer 3 properties displayed in the Layer 3 tab relate specifically to VPNs:

•Name—The name of the site, for example, ATM4/0.100(10.0.0.1) is a combination of the interface name and IP address used to reach the site. Each site belongs to a particular VPN, so the address must be unique within the VPN.

•IP Address—The IP address of the interface.

•Mask—The mask of the specific network.

•State—The state of the interface (up or down).

•VRF Name—The name of the VRF.

•Sending Alarms—Whether the alarm for the required port has been enabled (true) or disabled (false).

Cisco ANA PathTracer does not display or trace EXP bits for L3 VPNs that policy-based tunnel selection (PBTS).

Using Cisco ANA PathTracer for Layer 2 VPN

Cisco ANA uses VC ID and label switching information to trace the path from one tunnel interface to another over the MPLS network.

The Cisco ANA PathTracer also covers end-to-end Layer 2 VPN service paths from one CE router to another. The path goes over circuits (for example, a VC) or VLANs in the access networks and LSP between the Layer 2 tunnel edge.

The Cisco ANA PathTracer multipath window shows the VPN topology map for the relevant devices and links. From this window, you can open the Cisco ANA PathTracer single-path window with the appropriate VPN information displayed in the Layer 2 and Layer 3 tabs.

For Layer 2 path information, Cisco ANA uses VC ID and label switching information to trace the path from one tunnel interface to another. Layer 2 Cisco ANA PathTracer information is displayed in the Cisco ANA PathTracer window when the path goes over pseudowire tunnels.
