OpenFlow 1713
For replication of IP packets, at least one of (MAC-Src, MAC-dest and
VLAN-ID) should be valid.
L2 multicast is supported. It is done using IPMC L2 replication when all of
(MAC-Src, MAC-dest, VLAN-ID) action bucket fields are left empty. So
an "All (L3 Multicast) Group" can have a mix of buckets
few with L3
replication and few with L2 replication. To use the L2 multicast, the user
should not qualify the IP fields in flow match criteria.
Counters
The L3 Multicast group entry counters are as shown in Table 48-18.
Select (L3 ECMP) Group Type
L3 ECMP group entries are of OpenFlow type SELECT. For IP routing the
action buckets reference the L3 Unicast group entries that are members of
the multipath group for ECMP forwarding. Figure 48-3 illustrates this L3
ECMP Group entry usage.
Figure 48-3. L3 ECMP Group Entry Usage
An L3 ECMP Group entry can also be used in a Provider Edge Router.
