ARP/ND Suppression

Info

Notes:

  • ARP/ND suppression does not suppress RA/RS packets.
  • When configuring ARP/ND suppression, do not forget to configure the L3 VLAN interface corresponding to the VNI ID associated by VLAN ID.

           Example configurations:

Code Block
set vlans vlan-id 10
set vxlans vni 10010 vlan 10
set vlans vlan-id 10 l3-interface vlan10
set l3-interface vlan-interface vlan10
set vxlans vni 10010 arp-nd-suppress disable false

In MP-BGP EVPN networks, in order to suppress network storms caused by ARP/ND broadcast message flooding, ARP/ND suppression function can be enabled on VTEP devices to reduce network traffic.
