IPv4 and IPv6 Multicast 1527
Using DVMRP as the Multicast Routing Protocol
DVMRP is used to communicate multicast information between L3 switches
or routers. If a Dell Networking N1500, N2000, N3000, and N4000 Series
switches handles inter-VLAN routing for IP traffic, including IP multicast
traffic, multicast routing might be required on the switch.
DVMRP is best suited for small networks where the majority of hosts request
a given multicast traffic stream. DVMRP is similar to PIM-DM in that it
floods multicast packets throughout the network and prunes branches where
the multicast traffic is not desired. DVMRP was developed before PIM-DM,
and it has several limitations that do not exist with PIM-DM.
You might use DVMRP as the multicast routing protocol if it has already been
widely deployed within the network.
Microsoft Network Load Balancing
Dell Networking N-Series switches support Microsoft Network Load
Balancing (NLB) in unicast mode only. When using Microsoft NLB, ensure
that the Cluster Operation Mode is configured to the default value of
Unicast.
