· VXLAN IP gateways separated from VTEPs—Use a VXLAN-unaware device as a gateway to the external network for VXLANs. On the gateway, you do not need to configure VXLAN settings.

· VXLAN IP gateways collocated with VTEPs—Include the following placement designs:

¡ Centralized VXLAN IP gateway deployment—Use one VTEP to provide Layer 3 forwarding for VXLANs. Typically, the gateway-collocated VTEP connects to other VTEPs and the external network. To use this design, make sure the IP gateway has sufficient bandwidth and processing capability. Centralized VXLAN IP gateways provide services only for IPv4 networks.

¡ Centralized VXLAN gateway group deployment—Use one VTEP group that contains redundant centralized VXLAN IP gateways to provide reliable gateway services for VXLANs.

¡ Distributed VXLAN IP gateway deployment—Deploy one VXLAN IP gateway on each VTEP to provide Layer 3 forwarding for VXLANs at their respective sites. This design distributes the Layer 3 traffic load across VTEPs. However, its configuration is more complex than the centralized VXLAN IP gateway design. Distributed gateways can provide services for both IPv4 and IPv6 networks.

In a collocation design, the VTEPs use virtual Layer 3 VSI interfaces as gateway interfaces to provide services for VXLANs.

VXLAN IP gateways separated from VTEPs

As shown in Figure 1, an independent VXLAN IP gateway connects a Layer 3 network to a VTEP. VMs send Layer 3 traffic in Layer 2 frames to the gateway through VXLAN tunnels. When the tunneled VXLAN packets arrive, the VTEP terminates the VXLANs and forwards the inner frames to the gateway. In this gateway placement design, the VTEP does not perform Layer 3 forwarding for VXLANs.

Figure 1 VXLAN IP gateway separated from VTEPs

Centralized VXLAN IP gateway deployment

As shown in Figure 2, a VTEP acts as a gateway for VMs in the VXLANs. The VTEP both terminates the VXLANs and performs Layer 3 forwarding for the VMs.

Figure 2 Centralized VXLAN IP gateway placement design

As shown in Figure 3, the network uses the following process to forward Layer 3 traffic from VM 10.1.1.11 to the Layer 3 network:

1. The VM sends an ARP request to obtain the MAC address of the gateway (VTEP 3) at 10.1.1.1.

2. VTEP 1 floods the ARP request to all remote VTEPs.

3. VTEP 3 de-encapsulates the ARP request, creates an ARP entry for the VM, and sends an ARP reply to the VM.

4. VTEP 1 forwards the ARP reply to the VM.

5. The VM learns the MAC address of the gateway, and sends the Layer 3 traffic to the gateway.

6. VTEP 3 removes the VXLAN encapsulation and inner Ethernet header for the traffic, and forwards the traffic to the destination node.

Inter-VXLAN forwarding is the same as this process except for the last step. At the last step of inter-VLAN forwarding, the gateway replaces the source-VXLAN encapsulation with the destination-VXLAN encapsulation, and then forwards the traffic.

Figure 3 Example of centralized VXLAN IP gateway deployment

Centralized VXLAN gateway group deployment

As shown in Figure 4, a VTEP group uses redundant centralized VXLAN IP gateways to provide reliable gateway services for VMs in the VXLANs. All member VTEPs in the group participate in Layer 3 forwarding and load share traffic between the Layer 3 network and the VXLANs. This design distributes processing among multiple VTEPs and prevents single points of failure.

Figure 4 Example of centralized VXLAN IP gateway group deployment

The VTEP group is a virtual gateway that provides services at a group IP address. Access layer VTEPs set up VXLAN tunnels to the group IP address for data traffic forwarding. Each access layer VTEP also automatically sets up tunnels to the member IP addresses of VTEPs in the VTEP group. For all VTEPs in the VTEP group to have consistent forwarding entries, these tunnels are used for transmitting broadcast, multicast, and unknown unicast floods.

Distributed VXLAN IP gateway deployment

About distributed VXLAN IP gateway deployment

As shown in Figure 5, each site's VTEP acts as a gateway to perform Layer 3 forwarding for the VXLANs of the local site. A VTEP acts as a border gateway to the Layer 3 network for the VXLANs.

Figure 5 Distributed VXLAN IP gateway placement design

Figure 6 shows an example of distributed VXLAN IP gateway deployment. Create VSI interfaces on each distributed VXLAN IP gateway and the border gateway as gateway interfaces. Assign the same IP address to the same VSI interface on the distributed VXLAN IP gateways. Enable one of the following features on a distributed VXLAN IP gateway:

· ARP flood suppression. The gateway performs Layer 2 forwarding based on MAC address entries and performs Layer 3 forwarding based on ARP or ND entries.

· Local proxy ARP. The gateway performs Layer 3 forwarding based on ARP entries. The following sections use distributed VXLAN IP gateways enabled with the local proxy ARP or local ND proxy feature to describe the forwarding processes for intra-VXLAN traffic, inter-VXLAN traffic, and traffic from a VXLAN to an external network.

A distributed VXLAN IP gateway can generate ARP entries by a variety of methods. The following sections use dynamically learned ARP entries to describe the forwarding processes.

Figure 6 Example of distributed VXLAN IP gateway deployment

Intra-VXLAN traffic forwarding between sites

As shown in Figure 6, the network uses the following process to forward traffic in a VXLAN between sites (for example, from VM 1 to VM 4 in VXLAN 10):

1. VM 1 sends an ARP request to obtain the MAC address of VM 4.

2. GW 1 performs the following operations:

a. Creates an ARP entry for VM 1 and replies with the MAC address of VSI-interface 10 (the gateway interface for VXLAN 10).

b. Replaces the sender MAC address of the ARP request with the MAC address of VSI-interface 10, and then floods the request to all remote VTEPs.

3. VM 1 creates an ARP entry for VM 4. The MAC address in the entry is the MAC address of VSI-interface 10 on GW 1.

4. GW 2 (the VTEP for VM 4) performs the following operations:

a. De-encapsulates the ARP request and creates an ARP entry for VM 1. The entry contains VM 1's IP address (10.1.1.11), the MAC address of VSI-interface 10 on GW 1, and the incoming tunnel interface.

b. Replaces the sender MAC address of the request with the MAC address of VSI-interface 10 on GW 2, and then floods the request to the local site in VXLAN 10.

5. VM 4 creates an ARP entry for VM 1, and then sends a reply to GW 2. The MAC address in the ARP entry is the MAC address of VSI-interface 10 on GW 2.

6. GW 2 performs the following operations:

a. Creates an ARP entry for VM 4.

b. Replaces the sender MAC address of the request with the MAC address of VSI-interface 10 on GW 2, and sends the reply to GW 1.

7. GW 1 de-encapsulates the ARP request and creates an ARP entry for VM 4. The entry contains VM 4's IP address (10.1.1.12), the MAC address of VSI-interface 10 on GW 2, and the incoming tunnel interface.

8. For subsequent traffic between VM 1 and VM 4, GW 1 and GW 2 use their respective ARP tables to make the forwarding decision.

Inter-VXLAN traffic forwarding between sites

As shown in Figure 6, the network uses the following process to forward traffic between VXLANs (for example, from VM 1 in VXLAN 10 to VM 5 in VXLAN 20):

1. VM 1 sends an ARP request to obtain the MAC address of the gateway at 10.1.1.1.

2. GW 1 creates an ARP entry for VM 1 and replies with the MAC address of VSI-interface 10 (the gateway interface for VXLAN 10).

3. VM 1 sends the packet destined for VM 5 to GW 1.

4. GW 1 sends an ARP request to the local site and remote sites to obtain the MAC address of VM 5. In the ARP request, the sender IP address is 20.1.1.1, and the sender MAC address is the MAC address of VSI-interface 20 on GW 1.

5. GW 2 performs the following operations:

a. De-encapsulates the ARP request and creates an ARP entry for GW 1. The entry contains IP address 20.1.1.1 and MAC address of VSI-interface 20 on GW 1, and the incoming tunnel interface.

b. Replaces the sender MAC address of the request with the MAC address of VSI-interface 20 on GW 2, and then floods the request to the local site in VXLAN 20.

6. VM 5 creates an ARP entry for GW 2, and then sends a reply to GW 2. The entry contains the IP address (20.1.1.1) and MAC address of VSI-interface 20 on GW 2).

7. GW 2 performs the following operations:

a. Creates an ARP entry for VM 5.

b. Replaces the sender MAC address in the request with the MAC address of VSI-interface 20 on GW 2, and then sends the reply to GW 1.

8. GW 1 de-encapsulates the ARP request and creates an ARP entry for VM 5. The entry contains VM 5's IP address 20.1.1.12, the MAC address of VSI-interface 20 on GW 2, and the incoming tunnel interface.

9. For subsequent traffic between VM 1 and VM 5, GW 1 and GW 2 use their respective ARP tables to make the forwarding decision.

VXLAN-to-external network traffic forwarding

As shown in Figure 6, the network uses the following process to forward traffic from a VXLAN to the Layer 3 network (for example, from VM 1 to the host at 50.1.1.1):

1. VM 1 sends an ARP request to obtain the MAC address of the gateway at 10.1.1.1.

2. GW 1 creates an ARP entry for VM 1 and replies with the MAC address of VSI-interface 10 (the gateway interface for VXLAN 10).

3. VM 1 sends a packet destined for the host to GW 1.

4. GW 1 performs the following operations:

a. Searches the IP routing policies or routing table for the next hop. In this example, the next hop for the packet is 10.1.1.2 (the border gateway).

b. Floods an ARP request to the local and remote sites in VXLAN 10 to obtain the MAC address of 10.1.1.2.

5. The border gateway de-encapsulates the ARP request, creates an ARP entry for GW 1, and tunnels a reply to GW 1.

6. GW 1 de-encapsulates the ARP reply and creates an ARP entry for 10.1.1.2.

7. GW 1 sends the packet destined for the host to the border gateway.

8. The border gateway de-encapsulates the packet and forwards it to the host.

Restrictions and guidelines for distributed VXLAN IP gateway configuration

For a VXLAN that requires access to the external network, specify the VXLAN's VSI interface on the border gateway as the next hop by using one of the following methods:

· Configure a static route.

· Configure a routing policy, and apply the policy by using the apply default-next-hop command. For more information about configuring routing policies, see routing policy configuration in Layer 3—IP Routing Configuration Guide.

If both ARP flood suppression and local proxy ARP are enabled on a distributed VXLAN IP gateway, only local proxy ARP takes effect. As a best practice, do not use these features together on distributed VXLAN IP gateways. For more information about ARP flood suppression, see "VXLAN overview."

Make sure a VSI interface uses the same MAC address to provide service on distributed VXLAN IP gateways connected to IPv4 sites. Make sure a VSI interface uses different link-local addresses to provide service on distributed VXLAN IP gateways connected to both IPv4 and IPv6 sites.

Example: Configuring distributed VXLAN IPv4 gateways

Network configuration

As shown in Figure 8:

· Configure VXLAN 10, VXLAN 20, and VXLAN 30 as unicast-mode VXLANs on Router A, Router B, and Router C to provide connectivity for the VMs across the network sites.

· Manually establish VXLAN tunnels and assign the tunnels to the VXLANs.

· Configure distributed VXLAN IP gateways on Router A and Router C to forward traffic between the VXLANs.

· Configure Router B as a border gateway to forward traffic between the VXLANs and the WAN connected to Router E.

Procedure

1. On VM 1, VM 2, and VM 3, specify 10.1.1.1, 10.1.2.1, and 20.1.1.1 as the gateway address, respectively. (Details not shown.)

2. Configure IP addresses and unicast routing settings:

# Assign IP addresses to interfaces, as shown in Figure 8. (Details not shown.)

# Configure OSPF on all transport network routers (Routers A through D). (Details not shown.)

# Configure OSPF to advertise routes to networks 10.1.1.0/24, 10.1.2.0/24, 20.1.1.0/24, and 25.1.1.0/24 on Router B and Router E. (Details not shown.)

3. Verify that the network connectivity for VMs meets the requirements:

# Verify that VM 1, VM 2, and VM 3 can ping each other. (Details not shown.)

# Verify that VM 1, VM 2, and VM 3 can ping Ten-GigabitEthernet 0/0/6 (25.1.1.5) on Router E for WAN access. (Details not shown.)

Example: Configuring distributed VXLAN IPv6 gateways

Network configuration

As shown in Figure 9:

· Configure VXLAN 10 and VXLAN 20 as unicast-mode VXLANs on Router A, Router B, and Router C to provide connectivity for the VMs across the network sites.

· Manually establish VXLAN tunnels and assign the tunnels to the VXLANs.

· Configure distributed VXLAN IP gateways on Router A and Router C to forward traffic between VXLANs.

· Configure Router B as a border gateway to forward traffic between the VXLANs and the WAN connected to Router E.
