Example: Configuring DRNI and EVPN

distributed gateways (IS-IS for underlay

routing)

Network configuration

As shown in Figure 1:

•

Deploy a DR system at the border tier, and deploy two DR systems at the leaf tier. Configure

the DR systems as follows:

 Configure direct physical links as IPLs.

 Set up one border DR system with two HPE FlexFabric 12900E (Type X) switches.

Configure SDN gateways on the border DR system to forward traffic between the data

center and external network, and between PODs.

 Set up one leaf DR system with two HPE FlexFabric 5940 switches. Configure them as

SDN ToR switches and distributed EVPN gateways for network overlay.

 Set up another leaf DR system with two HPE FlexFabric 5945 switches. Configure them as

SDN ToR switches and distributed EVPN gateways for network overlay.

•

Configure two HPE FlexFabric 12900E (Type X) switches as spine devices. Configure them as

route reflectors to reflect BGP EVPN routes among border and leaf devices.

•

Configure the firewalls as follows:

 Configure them to operate in primary/secondary mode.

 Attach the firewalls to the border DR system by using four aggregation links of DR groups.

 Assign the firewalls to the same VLAN as the border DR system.

•

Configure static routes on the border DR system to direct the following traffic to the firewall for

security policy-based filtering or NAT:

 South-to-north traffic sent from the bare metal servers and VMs to the external network.

 Inter-VPC east-west traffic sent between the bare metal servers and VMs.

•

Configure the C-spine device to provide access to other data centers and forward Layer 3

traffic on the underlay network.

•

Configure the public device to provide access to the external network.

NOTE:

This example uses IS

-IS as the underlay routing protocol. Alternatively

, you can use OSPF or other

protocols for routing on the underlay network.

Traffic forwarding models

A VM is in a host overlay network, and a bare metal host is called a BM in network overlay. The

following traffic forwarding models are available:

•

Intra-VPC forwarding in the same POD (leaf > spine > leaf):

 VM-to-VM and VM-to-BM Layer 2 and Layer 3 communication through the same DR

system at the leaf tier.

 BM-to-VM and BM-to-BM Layer 2 and Layer 3 communication through the same DR

system at the leaf tier.

 VM-to-VM and VM-to-BM Layer 2 and Layer 3 communication across DR systems at the

leaf tier.

 BM-to-VM and BM-to-BM Layer 2 and Layer 3 communication across DR systems at the

leaf tier.

6

•

Inter-VPC forwarding in the same POD (leaf > spine > border > firewall > border > spine >

leaf):

 VM-to-VM and VM-to-BM Layer 3 communication through the same DR system at the leaf

tier.

 BM-to-VM and BM-to-BM Layer 3 communication through the same DR system at the leaf

tier.

 VM-to-VM and VM-to-BM Layer 3 communication across DR systems at the leaf tier.

 BM-to-VM and BM-to-BM Layer 3 communication across DR systems at the leaf tier.

•

Inter-POD forwarding (leaf > spine > border > C-spine > border > spine > leaf):

 VM-remote host and BM-remote host Layer 2 communication across PODs.

 VM-remote host and BM-remote host Layer 3 communication across PODs.

•

Forwarding between the data center and the external network (leaf > spine > border > firewall >

border > public device):

 Layer 3 communication between BMs and the external network.

 Layer 3 communication between VMs and the external network.

 SSH, FTP, and fping operations from the external network to the data center (leaf > spine >

border > LB > border > public device).

NOTE:

On an

will re

-establish neighbor relationships and perform route convergence. During the route

convergence process, routing loops and traffic loss might occur because t

he convergence speeds

of the nodes are different. To address this issue, enable IS

-

IS to advertise the maximum link cost to

neighbors within the specified period, so the traffic forwarding path remains unchanged. After the

specified period, IS

-IS advertises the original link cost to neighbors and performs optimal route

selection again.

NOTE:

If you use two border devices to set up

a DR system and BM

s in bond1 mode need to communicate

with the external network, unidirectional tunnels exist between the ToR switches and SDN gateway.

Typically, unidirectional tunnels are set up when a ToR switch is disconnected from the controller or

new

BMs come online. In this scenario, an online ToR switch advertises routes that contain its real

IP address. The SDN will set up a tunnel to that real IP address, while the ToR switch uses the

virtual VTEP IP address for tunnel setup.

For the ToR switches to

decapsulate the packets sent by

the SDN gateway, enable default VXLAN decapsulation on the ToR switches.
