You can configure IPv6 neighbor discovery (ND) attributes (MTU, M flag, O flag, and Prefixes) for each tenant network (ctag).
efa tenant epg create --name <epg-name> --tenant <tenant-name>
--ipv6-nd-mtu <ipv6-mtu>
--ipv6-nd-managed-config <true | false>
--ipv6-nd-other-config <true | false>
--ipv6-nd-prefix <ctag:list-of-prefix>
--ipv6-nd-prefix-valid-lifetime <ctag,prefix:validTime>
--ipv6-nd-prefix-preferred-lifetime <ctag,prefix:preferredTime>
--ipv6-nd-prefix-no-advertise <ctag,prefix:noadvertiseflag>
--ipv6-nd-prefix-config-type <ctag,prefix:configType(no-autoconfig| no-onlink | off-link)>
efa tenant epg update --name <epg-name> --tenant <tenant-name>
--operation <ctag-range-add | vrf-add | anycast-ip-add> --ctag-range <ctag-range> --vrf <vrf-name>
--anycast-ip <ctag:anycast-ip> --anycast-ipv6 <ctag:anycast-ipv6>
--ipv6-nd-mtu <ipv6-mtu>
--ipv6-nd-managed-config <true | false>
--ipv6-nd-other-config <true | false>
--ipv6-nd-prefix <ctag:list-of-prefix>
--ipv6-nd-prefix-valid-lifetime <ctag,prefix:validTime>
--ipv6-nd-prefix-preferred-lifetime <ctag,prefix:preferredTime>
--ipv6-nd-prefix-no-advertise <ctag,prefix:noadvertiseflag>
--ipv6-nd-prefix-config-type <ctag,prefix:configType(no-autoconfig| no-onlink | off-link)>
The following example configures IPv6 Neighbor Discovery (ND) on a Tenant Network:
