The CLM supports IPv4 or IPv6 communication with external clients, and internally among CLM entities, in single- and multiple-interface deployments. The NEs can communicate with the CLM using IPv4, IPv6, or both concurrently.

Some restrictions may apply in a multi-interface deployment; see CLM cluster multi-interface configuration for information.

Note: The use of compressed IPv6 addresses, for example, 2001:E7A3::6502:0DA8, is fully supported.
