Configure IP Interfaces for GigaSMART Tunnels

When you configure IP interfaces for GigaSMART tunnels:

  • You can associate the IP interfaces with multiple GigaSMART groups that are created either in the same node or in another node that resides in the same cluster.
  • You can associate multiple GigaSMART engines to a GigaSMART group.
  • You can also associate NetFlow exporters to the IP interface.

About IP Interface Centralization

A tunnel that originates from a node in a cluster can terminate on a remote port in another cluster. Also, a tunnel can have multiple termination points. You can associate the IP interface with multiple GigaSMART groups that are created either in the same node or in another node that resides in the same cluster. Moreover, you can associate multiple GigaSMART engines to a GigaSMART group.

The following figure illustrates the tunnel centralization feature.

 

1 Tunnel Centralization

In this example, a GigaVUE‑HC3, and GigaVUE-TA nodes reside in cluster A. In GigaSMART engines 1 and 2 are associated with the GigaSMART group 1. Similarly, in GigaVUE‑HC3, GigaSMART engines 3 and 4 are associated with GigaSMART group 2. An IP interface with alias 1_1_g1 is configured with a tool port in GigaVUE-TA. Both the GigaSMART groups, 1 and 2 are associated with the IP interface. The IP interface 1_1_g1 is the originating point for the tunnel, where encapsulation happens.

Now, let us look at the termination point of the tunnel. The GigaVUE‑HC1 a nodes reside in cluster B. In GigaVUE‑HC1-Plus, the GigaSMART engine 5 is associated with GigaSMART group 3 and in GigaVUE‑HC1, the GigaSMART engines 6 and 7 are associated with GigaSMART group 3. An IP interface with alias 1_1_g2 is configured with a network port in GigaVUE‑HC1-Plus. Both the GigaSMART groups, 3 and 4 are associated with the IP interface. The IP interface 1_1_g2 is the termination point for the tunnel, where decapsulation happens. Thus the tunnel terminates on a remote port in another cluster.

Note:  Do not attempt to configure with IP /Tunnel Interface and GigaVUE-FM Management Interface in the same subnet. As per routing functionality this is not a valid configuration.
