A‑Link and Private Network Requirements

A-Link and private networks, which are available only to dual-node systems, have the following requirements:

The networks use IPv6 link-local addressing.
All A-Link and private networks on one PM of a ztC Edge system must be in the same L2 broadcast domain as its matching links on the other physical machine (PM), without any protocol filtering.
Ethernet packets sent between two PMs of a system must not be obstructed or rate-limited. Ensure that they are not routed or switched by any L3 network infrastructure.
The speed of A-Link networks should be equal to or greater than the speed of business or management networks.
Network traffic for storage replication between PMs is sent over A-Link networks.
Private networks have no network hosts connected other than the ztC Edge end-points.
