Multi-VRF for NEMO

Multi-VRF for NEMO

This chapter explains how to configure network mobility (NEMO) by defining VRF Instances and configuring Multi-VRF for NEMO. Also allows you to set the user privacy and configure overlapping IP addresses on a mobile router. This chapter includes the following topic:

Multi-VRF for NEMO

Multi-VRF NEMO feature enables user privacy and supports overlapping IP addresses on a network mobility (NEMO) mobile router so that the devices or subnets connected to the NEMO mobile router seamlessly access multiple enterprise virtual routing and forwarding instances (VRFs), or multiple separate services across an access point name (APN).

Information About Multi-VRF NEMO

Dynamic Mobile Network Routing

Dynamic Mobile Network Routing (DMNR) is a network-based, mobile technology that provides dynamic routing, and support for mobile or stationary enterprise routers in primary wireless access or automatic wireless backup configurations. DMNR enables integration between wireless and wireline enterprise services that is, third generation (3G)Wireless WAN, by making use of the Mobile IPv4 network mobility (NEMO) protocol.

The mobile router is used with DMNR service for providing backup communications over Code Division Multiple Access (CDMA) or Evolution-Data Optimized (EVDO) Access and mobile private networks between an enterprise branch office and a data center connected to a IP MPLS/VPN network.

Multi-VRF NEMO feature enables privacy and supports overlapping IP addresses on a network mobility (NEMO) mobile router so that the devices or subnets connected to the NEMO mobile router seamlessly access multiple enterprise virtual routing and forwarding instances (VRFs), or multiple separate services across an access point name (APN).

Per-VRF Tunnel Template Support

Tunnel template support is available in this feature. A separate tunnel template is configured on a mobile router (MR) for each virtual routing and forwarding (VRF) instance, and the same tunnel template is applied on the tunnel created specifically for each VRF instance. The template is configured before the network mobility (NEMO) call is created.

How to Configure Multi-VRF NEMO

To configure Multi-VRF NEMO, you have to define VRF Instances and configuring Multi-VRF for NEMO:

Defining VRF Instances

Procedure
     Command or ActionPurpose
    Step 1 enable


    Example: 
    Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.

     
    Step 2 configure terminal


    Example: 
    Device> configure terminal
     

    Enters global configuration mode.

     
    Step 3 vrf definition vrf-name


    Example: 
    Device (config)# vrf definition red1
     

    Enters IP VRF configuration mode for defining a VRF routing table instance.

     
    Step 4 address-family ipv4


    Example: 
    Device (config-vrf)# address-family ipv4
     

    Enters VRF address-family configuration mode to configure a routing session using standard IPv4 address prefixes.

     
    Step 5 address-family ipv4


    Example: 
    Device (config-vrf-af)# exit-address-family
     

    Exits VRF address-family configuration mode and enters IP VRF configuration mode.

     
    Step 6 exit


    Example: 
    Device (config-vrf)# exit
     

    Exits IP VRF configuration mode and enters global configuration mode.

     
    Step 7Repeat the steps 3 through 6 to define another VRF instance. You can repeat these steps as many times as the required number of VRF instances.
