Configuring a centralized EVPN gateway

Configuration restrictions and guidelines

As a best practice, enable ARP flood suppression on VTEPs to reduce flooding.

Configuration procedure

Step
1. Enter system view.
2. Create a VSI
interface and enter
VSI interface view.
3. Assign an IPv4 or
IPv6 address to the
VSI interface.
4. Return to system
view.
5. Enter VSI view.
6. Specify the VSI
interface as the
gateway interface for
the VSI.

Configuring a distributed EVPN gateway

Configuration restrictions and guidelines
Make sure a VSI interface uses the same MAC address to provide service on distributed EVPN
gateways connected to IPv4 sites. Make sure a VSI interface uses different link-local addresses to
provide service on distributed EVPN gateways connected to both IPv4 and IPv6 sites.
If both ARP flood suppression and local proxy ARP are enabled on a distributed EVPN gateway, only
local proxy ARP takes effect. As a best practice, do not use these features together on distributed
EVPN gateways.

Configuration prerequisites

For a VXLAN to access to the external network, specify the VXLAN's VSI interface on the border
gateway as the next hop on distributed EVPN gateways 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 or apply
next-hop command. For more information about configuring routing policies, see routing policy
configuration in Layer 3—IP Routing Configuration Guide.
Command

interface vsi-interface vsi-interface-id
•
Assign an IPv4 address:
ip address ip-address { mask |
mask-length } [ sub ]
•
Assign an IPv6 address:
See IPv6 basics in Layer 3—IP
Services Configuration Guide.
