Example: Deploying DRNI and centralized

EVPN gateway

Network configuration

As shown in Figure 1, deploy two border devices as a DR system and use it as a centralized

gateway. The DR system provides intra-DC connectivity, external connectivity, and DCI.

The following is the network configuration:

•

Use DRNI to build the two border devices into a DR system. Configure the DR system as a

centralized EVPN gateway to provide L3 forwarding for VXLANs and as a border node to

provide connectivity to the external network.

•

Deploy two HPE FlexFabric 12900E switches at the spine tier. Configure them as route

reflectors (RRs) to reflect BGP EVPN routes among border and leaf devices.

•

Use DRNI to deploy two pairs of access switches (ToR) switches as DR systems at the leaf tier.

They provide EVPN access services to connect servers (for example, bare metal servers) to

their overlay networks.

Overlay connectivity models

The following are the types of connectivity between bare metal servers and between a bare metal

server and the external network:

•

Layer 2 connectivity between bare metal servers attached to the same DR system at the leaf

tier.

•

Layer 3 connectivity between bare metal servers attached to the same DR system at the leaf

tier.

•

Layer 2 connectivity between bare metal servers attached to different DR systems at the leaf

tier.

•

Layer 3 connectivity between bare metal servers attached to different DR systems at the leaf

tier.

•

Layer 3 connectivity between bare metal servers and the external network.

NOTE:

If

a DR system uses an Ethernet aggregate link as the IPL, each DR member device creates a

dynamic AC on the

IPL when an AC (Ethernet service instance) is configured on a site-facing

interface. The dynamic AC and the site

-facing AC have the same frame match criteria and VSI

mapping. If two site

-facing ACs on different interfaces have the same frame match criteria but

different VSI mappings, the dynamic ACs created for the site

-facing ACs will conflict with each

other. To prevent this issue, use the

l2vpn drni peer-link ac-match-rule vxlan-

mapping

command to enable the

DR member devices to create frame match criteria based on VXLAN IDs

for the dynamic ACs on the IPL.

IMPORTANT:

•

Make sure the DR member devices are consistent in global, IPP-specific, and

DRNI-interface-specific spanning tree settings. Inconsistent spanning tree settings might cause

network flapping.

•

IPPs in the DR system do not participate in spanning tree calculation.

•

After the DR system splits, the DR member devices still use the DR system MAC address to

send BPDUs, resulting in incorrect spanning tree calculation. To avoid this issue, enable DRNI

standalone mode on the DR member devices.
