Configure Global Parameters on Fabric IPsec Gateway VM

About this task

Perform this procedure to configure IPsec source IP address, Local Area Network (LAN ) interface IP and gateway IP address, maximum transmission unit (MTU) value, and so on globally, on the Fabric IPsec Gateway Virtual Machine (VM).

Note

You must perform this procedure only after the VM boots up.

1. Enter Fabric IPsec Gateway Configuration mode:

   enable

   virtual-service WORD<1-128> console

   

   Note

   Type CTRL+Y to exit the console.

2. Configure IPsec source IP address for a Fabric Extend (FE) tunnel for IPsec in decoupled mode:

   set global ipsec-tunnel-src-ip {A.B.C.D/X}

3. Assign VLAN ID to the configured IPsec source IP address:

   set global ipsec-tunnel-src-vlan <2-4059>

4. Configure the LAN interface IP address on the first Ethernet interface (eth0) of Fabric IPsec Gateway VM:

   set global lan-intf-ip {A.B.C.D/X}

5. Assign VLAN ID to the configured LAN interface IP address:

   set global lan-intf-vlan <2-4059>

6. Configure the LAN interface gateway IP address on the VOSS switch:

   set global lan-intf-gw-ip {A.B.C.D}

7. Configure the logical interface gateway IP address, to add routes for FE tunnels that need Fragmentation:

   set global fe-tunnel-gw-ip {A.B.C.D}

8. Configure the logical interface source IP address for the FE tunnel:

   set global fe-tunnel-src-ip {A.B.C.D}

   

   Note

   The logical interface source IP address must be same as the source IP address configured on the VOSS switch.

9. Configure the global MTU value:

   set global mtu <mtu-value>

   

   Note

   • The switch applies the global MTU value, if you do not configure MTU during the IPsec tunnel configuration.

   • If an IPsec tunnel is not using the fragmentation and reassembly capabilities, the default MTU value is 1950.
10. Configure the Wide Area Network (WAN) interface gateway IP address, which is the next hop for IPsec tunnels.

    set global wan-intf-gw-ip {A.B.C.D}

11. Configure the virtual reassembly interface IP address:

    set global virtual-reassembly-intf-ip {A.B.C.D/X}

    

    Note

    You must configure the virtual reassembly interface IP address to use the fragmentation and reassembly service.

12. Assign VLAN ID to the configured virtual reassembly interface IP address:

    set global virtual-reassembly-intf-vlan <2-4059>

13. Disable IPsec on all configured tunnels:

    set global ipsec-disable

14. Set IPsec log level:

    set global ipsec-log-level <-1-5>
