1 IP Networking: Part 2 Routing and Switching A webinar to help you prepare for the CBNE Certification Wayne M. Pecena, CPBE, CBNE Texas A&M University Office of Information Technology Educational Broadcast Services

2 "IP Networking: Part 2 Routing and Switching" Advertised Presentation Scope: IP Networking Fundamentals for Broadcast Engineers is an intensive instructorlead webinar series focused on major IP networking topics. The goal is to equip the broadcast engineer with the knowledge and understanding of IP networking fundamentals and the ability to apply conceptual theory in a practical manner. Today s webinar will focus on IP Routing & Switching. My Goals & Deliverables for This Afternoon: Provide an Understanding of IP Routing & Switching Fundamentals Know When to Switch & When to Route Understand Multicast Understand QoS Basics Provide a Foundation for SBE CBNT & CBNE Certification Exams Provide Reference Rf Material l& Resources to Obtain Further Knowledge 2

3 "IP Networking: Part 2 Routing and Switching Agenda Remembering the OSI Reference Model Switching Fundamentals Routing Fundamentals When Do I Switch When Do I Route? Unicast vs Multicast QoS Basics (broadcast oriented) Questions 3

4 POLL QUESTION Are you familiar with the OSI Reference Model, Ethernet Frame Structure, & IP Packet Structure? 4

5 OSI Model Refresher The OSI Reference Model is important to understanding networking terminology! 5

6 Ethernet Frame Layer 2 6

7 IP Packet Layer 3 RFC 791 7

8 Switching vs Routing When to Switch? When to Route? 8

9 Switching Fundamentals Switches Allow Segmentation of Network Allows Dedicated Bandwidth and Creates Point Point Communication Increased Throughput Due to Zero or Minimal Collisions Provides Full Duplex Operation Increased Security Capability Switches Selectively l Forward Individual id Frames from a Receiving ii Port to a Destination Port Builds Internal Table of Destination Address on each Port Forwards Ethernet Frame if in Table Floods Ports if Broadcast Frame 9

10 MAC Addresses Layer 2 Media Access Control MAC Address Unique Hardware Encoded Address Burned In Address Physical Address But Can Be Spoofed Hexadecimal Format: 12:3A:4D:66:3A:1C or FF FF FF FF FF FF Switches Learn a Table of MAC Addresses MAC Table Maps Destination MAC Addresses to a Port 10

11 A Simple MAC Table Example 11

12 Switching Types Forwarding Method Store and Forward Receives the Entire Frame Then Makes Decision Drops Any Errored Frame Based Upon CRC SLOW! (butinsures noframeerrors) errors) Cut Through Look Destination Address in Header of the Frame FAST! (but no error checking) Fragment Free (modified dcut Through) h) Known as Runt Free Switching 12

13 Virtual Local Area Network VLAN Logical Network of a Physical Network VLANS IEEE 802.1Q Allows Separation of Networks Across a Common Physical Media Creates Subset of Larger Network Control Broadcast Domains Each VLAN is a Broadcast Domain Architecture Flexibility Security Static Port Based VLAN(s) () Most Popular Manual Configuration Dynamic Port tbased MAC Based VLAN(s) Assignment Based Upon MAC Address Protocol Based VLAN(s) () Assignment Based Upon Protocol 13

14 VLAN Trunking 14

15 VLAN Identification IEEE 802.1Q 15

16 VLAN Example Switch Port Type Configuration: Access Link Member of One VLAN Only Connects to a Host Trunk Link Carries Traffic From Multiple VLANS Between Switches 16

17 Spanning Tree Protocol STP IEEE 802.1D Creates a Self Healing Network While Preventing a Broadcast Storm STP Operation: 1 - Determine Root Bridge 2 - Select Root Port 3 - Select Designated Ports 4 - Block Ports with Loops 17

18 Another Look at Spanning Tree Elected ROOT 1. Root Bridge Elected: - First Powered On - Priority Configuration - Lowest MAC Address Designated Ports Root Port Designated Port 2. Root Ports Identified Based Upon Path Cost Root Port 3. Designated Ports Identified Lowest Path Cost to Root 4. Port Blocked Designated Port with Highest Cost In The End: 1 Root per Network / 1 Designated Port per Segment / 1 Root Port per Non-Root Switch 18

19 POLL QUESTION Can I hookup up a PC with Ethernet monitoring software running to a vacant Switch port in order to monitor IP packets between Host 1 and Host 2? 19

20 Port Mirroring Analyze Sniff Data Flow Between Two Hosts 20

21 Managed vs Un Managed Ethernet Switches Managed Switch User Configurable Provides Ability to Control & Monitor Host Communications Port Configuration, Security, & Monitoring i VLAN Implementation Redundancy Supported (STP) QoS (Prioritization) Implementation Port Mirroring Un Managed Switch Fixed Configuration Plug & Play Provides Basic Host Communications Cheaper 21

22 Routing Routing is Simply the Moving of Data Between Networks OSI Model Layer 3 Process Routing Involves Two Processes: Determining thebestpath Actually Sending of the Data Routing Types: Static Routing Dynamic Routing Routing Protocols: Interior Gateway Protocol (IGP) Exterior Gateway Protocols (EGP) 22

23 Routing Routing Decisions are Based Upon Routing Protocols 23

24 Routing Types Static Routing Appropriate for Small Networks Appropriate for Stable Networks Use in Stub Networks Human Intervention Required Less Skill Needed Predictable Routing Topology Secure Minimal Hardware Dynamic Routing Appropriate for Changing Topology Environments Desirable When Multiple Paths Exist Applicable to Complex Environments Adapts to Topology Without Human Intervention More Scalable Less Configuration Error Prone Higher Skill & Knowledge Required Increased dhardware Required 24

25 Routing Fundamentals Routing is Simply Moving Data From One Network to Another Network 25

26 Dynamic Routing Determine the Best Path The Best Path Between Networks is Determined By Routing Algorithm Metrics Maintained in a Routing Table. Administrative Distance (AD) Trustworthiness of the Routing Information Route Source: Direct 0 Static 1 EIGRP 90 OSPF 110 RIP 120 Unknown 255 Administrative Distance (default) Highest Reliability 26

27 Routing Protocols: Routing Protocols: Interior Gateway Protocols (IGP) Used With Routers Under the Same Organizational Control Distance Vector Link State Exterior Gateway Protocol (EGP) The Routing Protocol of the Internet t(between ISP s) Interior Gateway Protocol Sample: RIP v1 & RIP v2 IGRP EIGRP OSPF Exterior Gateway Protocol Sample: IS-IS BGP v4 (BGP4) 27

28 Routing Metric Factors Hop Count The Number of Routers in a Path Bandwidth Throughput (bps) Load Traffic Flowing Through a Router Delay Network Latency (distance or congestion) Reliability Amount of Downtime of a Network Path Cost Administrator Assigned Smaller Metrics = Best Route 28

29 Distance Vector Routing Protocols Routing by Rumor The Overall Network is Unknown, Only Directly Connected Neighbors Are Known by Each Router Routing Decision i Based Upon a Distance or Metric and Direction or Vector to Describe the Next Hop 29

30 Simplified Distance Vector Routing Example: 30

31 Link State Routing Protocols Network Topology Information is Flooded Throughout the Network Each Router Determines its Own Best Path 31

32 Link State Algorithms More Efficient for Large Networks Maintains Topology of the Entire Network Only Forwards Updates When Changes Occur (OSPF Paranoia Updates Every 30 Minutes) Classless IP Addressing Supported Metrics More Complex Thus More CPU Overhead Fast Convergence No Hop Count Limits 32

33 Routing Protocols: Which One is Best? It Depends 33

34 Routing Protocol Choices Interior Distance Vector Interior Link State Exterior Path Vector Classful l RIP IGRP EGP Classless RIP v2 EIGRP OSPF v2 IS IS BGP v4 IPv6 RIPng EIGRP v6 OSPF v3 IS IS v6 BGP v4 Our Focus 34

35 Routing Protocols: Which One is Best? It Depends ISP BGP RIP OSPF EIGRP 35

36 Routing Protocol Selection Static Routing Dynamic Routing EGP IGP BGP Distance Vector Protocol: Link State Protocol: RIP IGRP OSPF IS-IS Standards Based Proprietary Hybrid Protocol: EIGRP 36

37 Practical Routing Protocol Choices Common IGP Protocols VLSM Support RIP v2 EIGRP (Cisco) OSPF v2 Type: Distance Vector Hybird Link State Metric: Hop Count Bandwidth/Delay Cost Administrative Distance: Hop Count Limit: None Convergence: Slow Fast Fast Updates: Full Table Every 30 Seconds Send Only Changes When Change Occurs Send Only When Change Occurs, But Refreshed Every 30m RFC Reference: RFC 1388 N/A RFC

38 Advantages: RIP v2 Routing Information Protocol RFC 1388 Simple Easy to Configure Low Maintenance General Understanding Of Disadvantages: Higher Router CPU Utilization High Bandwidth Use for Routing Updates No Knowledge of Link Bandwidth Slow Convergence Limited Network Size (hop count = 15) 38

39 Advantages: Fast Convergence Routing Updates Are Small Scales to Varying Network Sizes OSPF v2 Open Shortest Path First RFC 2328 Considers Link Bandwidth Into Metric Calculation Disadvantages: MoreKnowledge Required A lot ofoptions Complex to Configure 39

40 When to Switch? When to Route? When to ROUTE? To Create a Broadcast Domain Create Separate Networks Si When to SWITCH? Eliminate a Collision Domain 40

41 POLL QUESTION In order to minimize Broadcast IP packets From propagating between inter-connected networks, a Broadcast Domain can be created. A Broadcast Domain is created by what OSI Model layer? 41

42 What Is A Layer 3 Switch? Marketing Terminology Applied to a One Box Solution: Layer 2 Switching or Forwarding Traditionally Performed in Hardware Layer er3 Routing orforwarding Traditionally Performed in Software Layer 3 Switch Performs Both Not for All Environments Typically Found in Workgroup Environment Limited to Ethernet Limited to OSPF and RIP Protocols 42

43 Layer 3 Routing Switch Performs Layer 2 & Layer 3 Functions: Layer 2 Forwarding Performed: Destination MACAddress Address is different fromtheswitch MAC Address Layer 3 Forwarding Performed: Destination MAC Address is the same as the switch MAC Address No WAN Ports (Ethernet Only) 43

44 Layer 3 Routing Switch Operation 44

45 Multi Layer Switch Terminology Summarized Layer 1 Switch = Really Does Not Exist Often a Simple Hub Layer 2 Switch = Traditional Data Link Layer Switching Layer 3 Switch = Performs Layer 3 Forwarding Decisions Layer 4 Switch = Implements Transport Layer Flow Decisions Firewall VPN Concentrator Layer 7 Switch = Provides Applications Level Functionality Often Based Upon a Uniform Resource Locator (URL): Load Balancing Content Management 45

46 UNICAST vs MULTICAST Unicast 1 to 1 Model Traditional IP Communications Mode Does Not Scale Very Well Multicast 1 to Many Model or 1 to a Specific Group Traditional Broadcast Communications Mode Utilizes Routers to Replicate Packets Broadcast 1 to All 46

47 Multicast Terminology Key Points A Multicast IP Packet is Sent from a Server to a Group of Hosts A Host MUST Request Joining a Multicast Group Class D Address Space Allocated for Multicast to Ranges further allocated for specific purposes Routers Must Run a Multicast Routing Protocol IGMP Internet Group Management Protocol Allows Hosts to Request Joining a Multicast Group PIM Protocol Independent Multicast Routing Protocol lthat Distributes ib Multicast Packets Creates a Multicast Tree and Dynamically Prunes the Tree IMPORTANT NOTE Multicast Is Not Available Across the Internet Use is Limited to Local Network Segments in Most Cases 47

48 Unicast Environment 48

49 Multicast Tree Multicast Environment Multicast Clients Are Pruned as Multicast Streams Are No Longer Required 49

50 Multicast in a Broadcast Environment Diagram Courtesy of: 50

51 Quality of Service QoS IEEE 802.1P/Q Why QoS? All IP Packets Are Created Equal, But The Application Data Contained Within an IP Packet May Not Be. Q0S Allows Network Traffic to Be Prioritized Based Upon the Application to Insure Packet Delivery: Streaming Media (Audio over IP Video Over IP) IP Telephony (Voice over IP) Real Time Control (automation control) Mission Critical Applications 51

52 Why is QoS Important? Why is QoS Important for Broadcasters? Broadcasters Handle Real Time Media Create It, Manipulate It, Distribute It Network Factors Impacting Quality of Experience (QoE): Throughput Errors Dropped Packets Latency Jitter Packet Delivery Out of Order 52

53 Implementing QoS Implementation Architecture Packet Type Identification & Marking Network Element Provisioning End-End Policy Management 53

54 Priority Marking IEEE 802.1Q Preamble Destination Source Type Address Address Data FCS 8100h Priority VLAN ID 3 bits Priority Marking 54
