Introduction
This document gives an overview of the configuration required to establish a Generic Routing Encapsulation (GRE) tunnel routing Internetwork Packet Exchange (IPX) between two Cisco VPN 5000 Series Concentrators. For information about how to establish basic connectivity, or reference on configuration syntax, refer to the VPN 5000 Concentrator documentation. Testing for this document was done with routers configured for IPX on the internal networks.
Prerequisites
Requirements
There are no specific requirements for this document.

Verify
This section provides information you can use to confirm your configuration is working properly.
Certain show commands are supported by the Output Interpreter Tool ( registered customers only) , which allows you to view an analysis of show command output.
-
show vpn partners —Shows this information:
-
The VPN port number to which the peer is connected.
-
The tunnel peer's IP address.
-
The UDP port for the connection.
-
Whether the tunnel peer is connected to this VPN Concentrator's Tunnel Partner Default section instead of a specific Tunnel Partner section.
-
The IP address used as the local endpoint of the tunnel.
-
The duration that the partners have been connected.
-
-
show vpn statistics verbose—Shows this information for users and Partners and the total for both:
-
Current active connections.
-
Currently negotiating connections.
-
The highest number of concurrent active connections since the last reboot.
-
The total number of successful connections since the last reboot.
-
The number of tunnel starts.
-
The number of tunnels for which there were no errors.
-
The number of tunnels with errors.
-
-
show ipx routing—Shows the routing table in two sections. The first section is the network information for the directly-connected routes. The second section shows the dynamic routes obtained through IPX Routing Information Protocol (RIP) packets on the directly-connected networks.
-
show ipx servers—Shows the information in the Service Advertising Protocol (SAP) table, which is explained in this table:
Type
The server type.
Name
The server name.
Net Address
The IPX address (net - node) of the server.
Port
The port or socket number where the server is listening.
Hops
The number of hops away that the server is from this device. Values are between 1 and 16. If a hop count is 16, the server is timed out and will be purged from the table.
TTL
The Time to Live (TTL) for the service in seconds. A value of 999 means that the timeout is infinite and will never be timed out.
Iface
The interface through which information about the service is received. The interface where the service is located is also identified.
-
show ipx runtime—Displays command runtime IPX parameters.
This is sample command output of the show vpn partners command.
