I have created 2 Standard HB120rs v2(RDMA capable) Virtual Machines on Azure with centos-based HPC, On "ifconfig" I am getting below ips for 2 machines enter image description here

enter image description here

I tried testing rping using the below commands

On instance 1 executed

rping -v -s -a 172.16.1.66 -C 10

On instance 2 executed

rping -v -c -a 172.16.1.66 -C 10

On doing this I am getting below error

cma event RDMA_CM_EVENT_ADDR_ERROR, error -110
waiting for addr/route resolution state 1

rping is not working. How to connect between two Mellanox devices from 2 VMs in azure.
