4.4.4 DNOS-OF L3 Unicast Group Entries
DNOS-OF L3 Unicast group entries are used to supply the routing next hop and output interface for packet
forwarding. To properly route a packet from either the Routing Flow Table or the Policy ACL Flow Table, the
forwarding flow entry must reference a DNOS-OF L3 Unicast Group entry.
DNOS-OF L3 Unicast automatically includes the ALLOW-IN_PORT vendor extension property to allow packets
to be sent out IN_PORT. This property overrides the OpenFlow default behavior, which is to not forward a
packet to IN_PORT, and is inherited by chained group entries. It is not visible to the controller and hence
cannot be modified or read.
All packets must have a VLAN tag. A chained L2 Interface group entry must be in the same VLAN as assigned
by the DNOS-OF L3 Unicast Group entry.
4.4.4.1 Naming Convention
The naming convention for DNOS-OF L3 Unicast Group entries is shown in Table 52.
4.4.4.2 Action Buckets
The single action bucket is as shown in Table 53. All actions are required.
