DYNAMIC ROUTING

WHAT IS DYNAMIC ROUTING AND ITS TYPES:

 1.  Dynamic routing is the process of routing protocols running on the router communicating with neighbour routers.
2. This automatically created route by the router in a network with the help of protocols.

3. Once the path is determined, a router can route a routed protocol.

There are two protocols who is responsible for dynamic routing:-

1. Routing protocol:- it is used by router to send the update message or communicate with other router in a network.
2.Routed protocol:- it carry network traffic for routing protocols. Examples of routed protocols are ip, ipx, apple talk etc.

Types of routing protocols:-

1. IGP ( intergral gateway protocol):- it is a protocol that works within a logical boundry in term of CCNA/CISCO.this logical boundry is called autonomous system.Example:- RIP, IGRP, EIGRP, OSPF, IS- IS ,

  RIP:-  Routing information protocol .
  IGRP :- Internal gateway routing protocol .
  EIGRP:- Enhance interial gateway routing protocol .
  OSPF:- Open shortest path first.
  IS-IS :- Intermediate system- intermediate system .

2. EGP ( Exterial gateway protocol):- protocol that work between two autonomous system is called EGP. Like:- BGP (Border gateway protocol) .

  RIP(Routing Information Protocol):-

     1.It is a Open System Protocols ,mean can run at any router easily.

 2. it is classfull routing protocols(mean not carry subnet mask).

 

3. RIP only uses hop count to determine the best way to a remote network, but it has a maximum allowable hop count of 15, meaning that 16 is deemed unreachable.

 

4. Administrative distance value of rip is 120 .

 

5.RIP support UDP port n. 520

6. Routing Information Protocol (RIP) is a true distance-vector routing protocol.

 

7. load ballancing up to 4 equal part .

 

8. exchange entire routing table for every 30 second.

 

9. It works on application layer .and have two types Ripv1 and Ripv2.

 

DIFFERENTIATE BETWEEN RIP-V1 AND RIP-V2.

 

RIP-V1                                             1. It is classfull.  2.Broadcaste 225.255.255.255 3. No authentication support. 4. Not support summerisation. 5. it support v1 and v2 both.

RIPV2     1.It is classless.     2. Multicast  224.0.0.9     3. support  Authentication.     4. Support auto summurised and mannual summerised.
