Note Non-routable IP addresses include IPv6 link-local addresses and Automatic Private IP Addressing (APIPA) IPv4 addresses.
Consider the following example scenario:
- The SMB client has the following configuration:
- Multiple network interfaces are available and enabled for both IPv4 and IPv6.
- A static routable IPv4 address is configured for each network interface.
- The only IPv6 address assigned to each network interface is a link-local address.
- The network interfaces are RSS capable.
- The SMB server has the following configuration:
- A single network interface is available and is enabled for IPv6 only.
- The only IPv6 address that is assigned to the network interface is a link-local address.
- The network interface is RSS-capable.
In the example scenario, only one network interface (interface A) is used for the SMB session because the link-local addresses of the other interfaces are ignored by SMB Multichannel, and the client can connect only to the link-local address of the server. Additionally, only one TCP/IP connection is created for interface A because the link-local address of A is ignored by SMB Multichannel, and the client can connect only to the link-local address of the server.
- Configure routable IP addresses for network interfaces that must take advantage of SMB 3.0 Multichannel.
- Configure only non-routable IP addresses (APIPA or link-local addresses) for network interfaces that must take advantage of SMB 3.0 Multichannel.
- The first method is the recommended workaround.
- In the second method, both the SMB client and SMB server must be on the same network segment because the IP addresses are non-routable.
