	shortest path to each hop.	OSPF provides less “Network
		Chatter” and can scale into
		larger environments.

CIDR	Provides a single IP address
	that can be used to designate
	many unique IP addresses.
IRDP	Helps the PowerConnect
	6024/6024F to discover the IP
	addresses of their neighboring
	routers.
ICMP	Used for out-of-band messages
	related to network operation or
	malfunction.
VRRP	Virtual Router Redundancy
	Protocol is used to replicate
	routing tables between routers.
ARP	A TCP/IP protocol used to
	convert an IP address into a
	physical address.
IGMP	The standard protocol for
	Multicast traffic.
DVMRP	Distance Vector Multicast
	Routing protocol.
Static Routes	Allows the user to manually
	enter static addresses of other
	network routes.
802.1Q VLAN	Virtual LANs combine a number
	of ports into distinct, separated
	sub-networks. GVRP allows for

Helps reduce the size of routing tables and makes more IP addresses available.

Provides the ability to track dynamic changes in router availability.

Helps routing devices to communicate with each other to determine the network status.

Defines a master and backup routers to maintain a copy of the networks routing table. The backup router is elected if the master is no longer available.

Allows a routing device to determine the physical addresses of other devices connected to it.

The protocol allows a host to inform its local router, using Host Membership Reports, that it wants to receive messages addressed to a specific multicast group.

Allows the network to advertise the shortest-path (as counted in hops).

Provides an easy method to recording known hops in small or static networks.

Allows for limitation of broadcast domains as well as improved security. GVRP
