Firstly well be requiring static IPs from ISP for each of the routers from individual branches, then build a GRE tunnel and can use Ipsec:Crypto for encryption purposes. thus building a secured tunnel i.e. Private communication over public infrastructure.

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.
