Symptom

While testing HA configuration and attempting to ping between the HA2 interfaces, ping does not succeed and displays the message below:

 

Bind: Cannot assign requested address

 

Cause

The HA2 link is used to synchronize sessions, forwarding tables, IPSec security associations and ARP tables between devices in an HA pair. Data flow on the HA2 link is always unidirectional and thus cannot be designated to issue a ping.
