Git- Part 1: Intro to Git

Introduction: What is Version Control?

● Version Control System (VCS) is a system used for tracking

changes to content (aka source control).

● Crucial for collaboration:

◆ Who made the change?

◆ What was the change?

◆ When was the change made?

Policy-Based Routing (PBR), How PBR works and How we can use PBR?

PBR:

  • Destination based routing systems make it quite hard to change the routing behavior of specific traffic. With PBR, a network engineer has the ability to dictate the routing behavior based on a number of different criteria other than destination network, including source or destination network, source or destination address, source or destination port, protocol, packet size, and packet classification among others.
  • Policy-based routing adds flexibility and control that other routing techniques do not. It give you a level of control that a routing protocol by itself does not.
  • With flexibility, there is typically a cost and in this case its scalability and manageability.
  • It is a great tool but not one to be used for all cases. When you have a need to forward base on something other than destination, then PBR is your answer.
  • In a way, it allows traffic engineering at interface level. It allows to route the packets over specific traffic engineered paths, which provide the desired QoS through the network.

Redistributing into OSPF

OSPF is a standardized Link-State routing protocol that uses cost (based on bandwidth) as its link-state metric. An OSPF router performing redistribution automatically becomes an ASBR

Route Redistribution Basics

It is preferable to employ a single routing protocol in an internetwork environment, for simplicity and ease of management. Unfortunately, this is not always possible, making multi-protocol environments common.

Route Redistribution allows routes
