A multicast mesh is a type of routing for ad hoc networks. Imagine a collection of say, 1000 laptops and smart-phones. Now, imagine that we want to send a message from any one device to any other. There are two routing types that immediately come to my mind: multicast tree and multicast mesh.
multicast tree: a device will only accept and forward a message from sender to receiver IF that router is on the shortest path from sender to receiver (basically, there are some more details). This routing protocol eliminates multicast loops (good) and nearly optimally provides the shortest route from sender to receiver. However, since this is an ad hoc network, a device on that path can turn off. When this happens (and it will), the entire ad hoc network has to send control messages to every device so that they know what tree they are on. This sucks, because it is a lot of overhead, and will happen frequently.
multicast mesh: Each device accepts messages even if the device is not on the shortest path from sender to receiver. This provides richer connectivity, and is robust when devices come and go. However, there is a problem, richer connectivity also means poor bandwidth utilization (there are duplicate messages in the network). Also, a purely multicast mesh network does not scale well (control messages + duplicate messages mire the network as nodes increase).

Which class of IP addressing is being used when multicast messages are being sent?
For multicast, ip addresses in the range of 224.0.0.0 - 239.255.255.255 are used.
What type of address is 01-00-5E-0A-00-02?
It's a multicast address to be multicast to a group of hosts
What is multicast traffic?
Multicast traffic is traffic that is sent once, but for multiple recipients. Certain pieces of equipment will re-send the multicast traffic to anyone interested in receiving them.Multicast traffic is traffic that is sent once, but for multiple recipients.

What is last usable ip address?
The highest usable IP address for non-multicast devices is 223.255.255.254 The highest usable multicast IP address is 239.255.255.254
What is multicast routing?
Multicast routing is done by sending one packet to several destinations (those destinations were announcing their interest by joining the multicast group). See [multicast].
What is the range for globally scoped multicast addresses?
Multicast IP range is 224.0.0.0 - 239.255.255.255
What is multicast authentication?
multicast authentication is the effective method of delivering data from sender to multiple receivers..

What are the globally scoped multicast addresses?
unique addresses that are public domain addresses
What is mutlicast?
Perhaps you mean multicast? Multicast refers to computer networking, and is the simultaneous transmission of data to several destinations on a network.
What type of address is 01-00-5E-0A-00-02?
It's a multicast address to be multicast to a group of hosts
What is the eigrp multicast address?
224.0.0.10
What addresses do multicast start with?
All multicast addresses begin with "1110" as shown. The "well-known" group has zeroes for the first 20 bits of the multicast group address, with 8 bits available to define 255 special multicast addresses. Multicast addresses starting with "1110 1111" are locally-scoped; all other addresses are globally-scoped (this includes addresses starting with "1110 0000" other than the 255 "well-known" addresses.)

What is an important difference between implementing the multicast abstract via multiple unicasts and a single network router supported multicast group?
multicast is group communication where information is addressed to a group of computers where unicast packet is sent from a single source to a single destination .
