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
Classless routing -> Routing that sends subnet mask information in the routing updates. Classless routing allows VLSM (Variable Length Subnet Masking)
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.
Mulitcasting -> Any Communication between a single sender and multiple receivers.In Networking Multicast
messages are sent to a defined subset of the network addresses.
VLSM -> Is nothing but Variable Length Subnet mask.It is the process of subnetting the subnetted
addMulticasting: Is nothing but sending the message to particular number of computer in side the
LAN or outside the LAN.
