Routing protocol

Routing protocol configuration (Short note and Example):

Note: I will try to make this document. You will see all documents very soon……

Routing protocol types:

1. Static routing (AD - 1)

2. Default routing

3. Dynamic routing (Two type of dynamic Interior Gateway Protocol (IGP) & Exterior Gateway Protocol (EGP))

   3.1. Interior Gateway Protocol (IGP): An interior gateway protocol (IGP) is a routing protocol that is used to exchange routing information within an autonomous system (AS). Two type of IGP – Distance Vector & Link State routing protocol.

          3.1.1. Distance-Vector routing protocol:

                3.1.1.1. Routing Information Protocol (RIP)(V1, V2)(AD-120)(224.0.0.9)(UDP 520)

                3.1.1.2. Interior Gateway Routing Protocol (IGRP) (AD - 100)

                        

          3.1.2. Link State routing protocol:

                 3.1.2.1. Intermediate System To Intermediate System (IS-IS):  (AD - 115)

                 3.1.2.2. Open Shortest Path First (OSPF)(AD-110) (224.0.0.5)

          3.1.3. Hybrid Routing Protocol:
                 3.1.3.1. Enhanced Interior Gateway Routing Protocol -(EIGRP)(224.0.0.10)

                 (AD-Internal EIGRP-90, External EIGRP-170), Its Cisco proprietary

     
    3.2. Exterior Gateway Protocol (EGP): (AD - 140), Path Vector Routing Protocol, BGP is Exterior Gateway Protocol. BGP have two types (1-64511 Public AS, 64512-65535 Private AS)

                 3.2.1. Internal Border Gateway Protocol (IBGP): (AD - 200)

                 3.2.2. External Border Gateway Protocol (EBGP): (AD - 20)
