VCE-HA - WAN connection with a /29 block of IP Addresses

Hello,

Why do we need individual WAN links with a block /29 of IP Addresses for a VMware SD-WAN High-Availability (HA) mode setup?

Can this HA setup be achieved if we only have /30 IPs on both WAN links? 

Thanks.

Hi @JPScolar1 ,

From the topology I'm assuming that you wanna setup the Standard HA topology.

I think you can implement the /30 IPs on both WAN links, since the Standard HA was Active-Standby redundancy.
