Hi! Michael

Thanks for your advice, I mean could 2*cisco devices support just use only
one identical address?

...
interface Vlan100
vrf v101
ip address virtual 192.168.100.254/24
interface Vlan101
vrf v101
ip address virtual 192.168.101.254/24

Hi, Chen,

The Arista configuration snippet you sent over is related to implementation
of VXLAN distributed anycast gateway, not a traditional FHRP like HSRP,
VRRP, or GLBP. In a standard VRRP configuration on Arista, Juniper or
anything, one would expect to use multiple IPs for master and backup
nodes/roles.

You can implement this same configuration for Nexus following the
configuration documentation for VXLAN anycast gateway.

Thank you,
Nathan
