NICAST OUTING
The BlackDiamond can route IP traffic between the VLANs that are configured as
virtual router interfaces. Both dynamic and static IP routes are maintained in the
routing table. The following routing protocols are supported:
• RIP version 1
• RIP version 2
• OSPF

ULTICAST OUTING
The BlackDiamond can use IP multicasting to allow a single IP host to transmit a packet
to a group of IP hosts. The BlackDiamond supports multicast routes that are learned by
way of the Distance Vector Multicast Routing Protocol (DVMRP).

ETWORK ONFIGURATION
The BlackDiamond can be used as a core network switch, a segment switch, or a server
switch. When used as a core network switch, the BlackDiamond performs
collapsed-backbone routing and switching at wire-speed, allowing it to handle the
growing influx of intranetwork and Internet traffic that travels between multiple
networks.
When used as a high-density segment switch in the wiring closet, the BlackDiamond
can aggregate the hierarchy of legacy hubs and switches that support desktop
connections. When the BlackDiamond is used to perform segment switching at Layer 3,
local traffic stays within the subnet and does not needlessly enter the core.
