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


Note

NEMO Mobile IP does not work in Cisco IOS XE Everest16.4.1.

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

Defining VRF Instances

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. vrf definition vrf-name
  4. address-family ipv4
  5. address-family ipv4
  6. exit
  7. Repeat 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.

DETAILED STEPS

  Command or Action Purpose
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 7

Repeat 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.

  13. end

DETAILED STEPS

  Command or Action Purpose
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

ip mobile router

Example:

Device> ip mobile router

Enables the mobile router and enters mobile router configuration mode.

Step 4

address address mask

Example:

Device (mobile-router)# ip mobile router

Enables the mobile router and enters mobile router configuration mode.

Step 5

address address mask

Example:

Device (mobile-router)# address 10.2.2.2 255.255.255.255

Sets an IP address for the tunnel source interface.

Step 6

home-agent ip-address [ priority level]

Example:

Device (mobile-router)# home-agent 10.1.1.1

Specifies the home agent that the mobile router uses during registration.

Step 7

mobile-network interface interface-number

Example:

Device (mobile-router)# mobile-network Ethernet 0/3

Specifies the mobile router interface that is connected to the dynamic mobile network.

Step 8
