Network Restrictions

Ensure that IPv4 and IPv6 addresses are configured on XCO management Interface. Adding an IPv4 address is mandatory during sub-interface creation; IPv6 addresses are optional.

Do NOT use the following IPv4 or IPv6 address subnets. These are either not supported or reserved for K3s:

• 10.42.0.0/16 subnet
• 10.43.0.0/16 subnet
• 169.254.0.0/16 subnet
• fd42::/48 subnet
• fd43::/112 subnet
• Do not use IPv4 mapped IPv6 addresses.
  

      Format: 0:0:0:0:0:FFFF:w.x.y.z or ::FFFF:w.x.y.z
  
      Example: ::ffff:10.10.10.10or ::ffff:0a0a:0a0a
      ```

• Do NOT use IPv6 Link Local addresses.
• The requirement for IPv4 or IPv6 default routes depends on the IP stack selected.
