To receive IPv6 Multicast messages on VM, explicitly set the relevant
MAC address using rte_eth_dev_mac_addr_add() API.
- E-Switch VXLAN tunnel is not supported together with outer VLAN.
- E-Switch Flows with VNI pattern must include the VXLAN decapsulation action.
- E-Switch VXLAN decapsulation Flow:
- can be appiled to PF port only.
- must specify VF port action (packet redirection from PF to VF).
- must specify tunnel outer UDP local (destination) port, wildcards not allowed.
- must specify tunnel outer VNI, wildcards not allowed.
- must specify tunnel outer local (destination) IPv4 or IPv6 address, wildcards not allowed.
- optionally may specify tunnel outer remote (source) IPv4 or IPv6, wildcards or group IPs allowed.
- optionally may specify tunnel inner source and destination MAC addresses.
- E-Switch VXLAN encapsulation Flow:
- can be applied to VF ports only.
- must specify PF port action (packet redirection from VF to PF).
- must specify the VXLAN item with tunnel outer parameters.
- must specify the tunnel outer VNI in the VXLAN item.
- must specify the tunnel outer remote (destination) UDP port in the VXLAN item.
- must specify the tunnel outer local (source) IPv4 or IPv6 in the , this address will locally (with scope link) assigned to the outer network interace, wildcards not allowed.
- must specify the tunnel outer remote (destination) IPv4 or IPv6 in the VXLAN item, group IPs allowed.
