!Redistribution is doing where when we need to pump our routes to different protocol

!RIP redistribution is available for following protocols in Cisco IOS 15

Router(config-router)#redistribute ?
connected  Connected
eigrp      Enhanced Interior Gateway Routing Protocol (EIGRP)
metric     Metric for redistributed routes
ospf       Open Shortest Path First (OSPF)
rip        Routing Information Protocol (RIP)
static     Static routes

!RIP to EIGRP

Router(config-router)#redistribute eigrp <AS> metric <default-matric>

!RIP to OSPF
Router(config-router)#redistribute ospf <process-ID> metric <default-metric>

comes under System.delegates
type of variable which keeps references to methods
defines return type and parameter list

Example:

class Program
{
//declaring delegate
delegate double calc(num1,num2);

public double addition(num1,num2)//same signature
{return num1+num2;}

public double minus(num1,num2)//same signature
{return num1-num2;}
}

class MainClass
{
private static void main(string[] args)
{
calc delObj;//created object with delegate
string input=Console.readLine();
if(input=='Add')
{
//instantiate delegate with reference to addition
delObj=new delObj(addition);
}
else
{
//instantiate delegate
delObj=new delObj(minus);
}

//call delegate
delObj(10,20)
}
