Configure Suppress Address Resolution Protocol and Neighbor Discovery on VLAN or Bridge Domain

You can configure suppress address resolution protocol and neighbor discovery on VLAN or Bridge Domain.

Before you begin

Provide an option to enable or disable suppress ARP (suppress address resolution protocol) or ND (neighbor discovery) at the tenant network level so that you can choose to enable suppress ARP or ND per tenant network.

This option is mainly useful for a single rack small data center deployment where the suppress ARP or ND configuration on tenant network is not needed.

About this task

Follow this procedure to configure suppress address resolution protocol and neighbor discovery on VLAN or Bridge Domain

Note

XCO configures the suppress ARP or ND on the VLAN or BD (Bridge Domain) associated with the L3 tenant networks belonging to the distributed router.
XCO does not configure the suppress ARP or ND on the VLAN or BD associated with the L2 tenant networks.
For all the L3 tenant networks belonging to the distributed router, suppress ARP or ND is displayed as “true” after the upgrade from 2.4.x to 2.5.5.
For all the L3 tenant networks belonging to the centralized router, suppress ARP or ND is displayed as “false” after the upgrade from 2.4.x to 2.5.5.
For all the L2 tenant networks, suppress ARP or ND is displayed as “false” after the upgrade from 2.4.x to 2.5.5.

Procedure

To configure suppress ARP or ND for performance tuning when you create a VLAN or BD, run the following command:

efa tenant epg create --name <epg-name> --tenant <tenant-name> 
       --port <port-list> --switchport-mode <trunk|access> --ctag-range <ctag-range> 
       --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6> --vrf ten1vrf1
       --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
 efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation vrf-add 
        --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>  --vrf ten1vrf1
        --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation ctag-range-add 
       --ctag-range <ctag-range> --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>
       --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
 efa tenant epg update --name <epg-name> --tenant <tenant-name> --operation anycast-ip-add 
	  --anycast-ip <ctag:anycast-ipv4> --anycast-ipv6 <ctag:anycast-ipv6>
        --suppress-arp <ctag:true|false> --suppress-nd <ctag:true|false>
