L3 nHop Network Topology

L3 n Hop shows all active devices that can be reached from a selected starting device in the network through a chosen number of routed Level 3 connections. In the resulting graph, the name of the starting device is highlighted in green. Devices that cannot be reached, or that are farther away than the Hop Count are not shown in the resulting view. The information conveyed here can be considered a superset of the Path Analysis feature, which shows the preferred L3 routed path from the selected stating device to a defined destination device.

1. In the left panel, click L3 n Hop.
2. In the left panel, click the row containing the starting device.
3. In the L3 n Hop dialog, select a Hop Count and a Protocol.
4. Click OK.

Note: L3 connections are directional; a hop to a neighboring router and back is considered two hops. If you set Hop Count to 1, you won't see any return hops to the starting device.

Juniper M5 and M10 routers that are running virtual device contexts will have their VDCs appear in this list, appearing as any other router.
