1) Classful & Classless routing
Classful routing : Routing Protocol that do not send subnet mask information when a route update is sent out. All devices in the network must use the same subnet mask
Eg : RIP V1
Classless routing : Routing that sends subnet mask information in the routing updates. Classless routing allows VLSM (Variable Length Subnet Masking)
Eg : RIP V2 , EIGRP , & OSPF.
2) Difference between RIP V1 & RIP V2.
RIP V1 : Distance Vector , Maximum Hop count of 15 , Classful , No Support for VLSM , No support for Discontigious networks.
RIP V2 : Distance Vector , Maximum Hop count of 15 , Classless , Supports VLSM networks , Supports Discontigious networks
3) Mulitcasting : Any Communication between a single sender and multiple receivers.
In Networking Multicast messages are sent to a defined subset of the network addresses.
