Hi @sadanjan mallireddy,
by default Zookeeper Server binds(listens) to all the IPs/interfaces specified in the host,
on the reverse case, we can control this behavior by adjusting the parameter clientPortddress="required only IP/host name"
Abstract from Zookeeper documentation
clientPortAddress
New in 3.3.0: the address (ipv4, ipv6 or hostname) to listen for client connections; that is, the address that clients attempt to connect to. This is optional,
by default we bind in such a way that any connection to the clientPort for any address/interface/nic on the server will be accepted.
from this, you can redirect the required traffic to another nic (as long as the firewall allows).
Hope this helps !!
