Adding an additional subnet route

This topic describes how to add a new route for the IBM® support network after the VPN connection has been established using the IBM Connection Manager.

Context

Perform the following steps to add an additional subnet route.

Steps

  1. Determine the support network IP address of the master console:
    1. Click Start —> Programs —> Accessories —> Command Prompt.
    2. Enter ipconfig /all. The end of the listing will look similar to the following example:
      PPP adapter IBMVPN:
      
              Connection-specific DNS Suffix  . :
              Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
              Physical Address. . . . . . . . . : 00-53-45-00-00-00
              DHCP Enabled. . . . . . . . . . . : No
              IP Address. . . . . . . . . . . . : 198.74.64.60
              Subnet Mask . . . . . . . . . . . : 255.255.255.255
              Default Gateway . . . . . . . . . :
              DNS Servers . . . . . . . . . . . :
  2. Determine the support network interface number (IF) by entering route print. The beginning of the routing table will look similar to the following example:
    ======================================================================
    Interface List
    0x1 ........................... MS TCP Loopback interface
    0x1000003 ...00 02 55 7b 0c 09 ...... Intel(R) 82546EB Based Dual Port
                                          Network Connection
    0x1000004 ...00 02 55 7b 0c 08 ...... Intel(R) PRO/1000 MT Dual Port
                                          Network Connection
    0x2000004 ...00 53 45 00 00 00 ...... WAN (PPP/SLIP) Interface
    ======================================================================

    The support network interface is identified as the WAN (PPP/SLIP) Interface. The number given is in hex and must be converted to decimal (for example, 0x2000004 (hex) = 33554436 (decimal)).

  3. Add the new route for the support network by entering the following command:

    route ADD 198.74.64.0 MASK 255.255.252.0 [remote_support_IP]
    IF [IF_decimal_number] Metric 2

    Where remote_support_IP is the master console IP address determined in step 1 and IF_decimal_number is the interface number determined in step 2 (for example, route ADD 198.74.64.0 MASK 255.255.252.0 168.74.64.60 IF 33554436 Metric 2).

  4. Verify that the new route was added by entering route print and finding the 198.74.64.0 255.255.252.0 entry in the table. The output will look similar to the following:
    ===========================================================================
    Interface List
    0x1 ........................... MS TCP Loopback interface
    0x1000003 ...00 02 55 7b 0c 09 ...... Intel(R) 82546EB Based Dual Port 
                                          Network Connection
    0x1000004 ...00 02 55 7b 0c 08 ...... Intel(R) PRO/1000 MT Dual Port Network 
                                          Connection
    0x2000004 ...00 53 45 00 00 00 ..... .WAN (PPP/SLIP) Interface

  5. Verify routing to the support network by entering ping 198.74.67.235.
