VMware NSX

Hello

please when creating a logical Router i should configure HA interface , my question is what is the aim of HA interface and to which network i should connect  , and how i make sure that is working normally ?

Thanks :smileyhappy:

Primarily used for heartbeat communication between the Edges which are in HA mode. By default it takes link local ip,however you can configure separate IP for heartbeat communication,just ensure that you don't use those IP's anywhere in your NSX environment.

It is not a LIF, it’s local to the Control VM and does not require an IP address assigned.  However,  even if you configure one you wouldn’t be able to reach it via a routing protocol because there’s Reverse Path Forwarding (RPF) enabled.  

Please refer to KB: http://kb.vmware.com/kb/2122060 which explained in detail regarding the same.

Thanks,

When you deploy your edge in HA mode, there will be two edges deployed (one Active edge and one Standby edge).

The HA interface is used by the two edges to send heartbeat messages to each other, primarily for the Standby edge to detect if the Active edge is failed.

You can connect the HA interface to either a distributed port group (VLAN) or a logical switch (VXLAN), which is depicted in these topologies:

To verify the Heartbeat and the HA status, you can use the following command on one of the edge's console:
