IPv6 over IPv4 tunnel configuration notes

  • The local tunnel configuration must include both source and destination addresses.
  • The remote side of the tunnel must have the opposite source/destination pair.
  • A tunnel interface supports static and dynamic IPv6 configuration settings and routing protocols.
  • Duplicate Address Detection (DAD) is not currently supported with IPv6 tunnels. Make sure tunnel endpoints do not have duplicate IP addresses.
  • Neighbor Discovery (ND) is not supported with IPv6 tunnels.
  • If a tunnel source port is a multi-homed IPv4 source, the tunnel will use the first IPv4 address only. For proper tunnel operation, use the ip address option.
Note: ICX 7150 devices do not support tunnels.
