Logical Representation using a Server as an Application Gateway

Implementing Virtualization with Firewall Context

A Firewall runs in Either Transparent or Route Mode

Example use of a Firewall in Transparent Mode

A Server Load Balancer represents Multiple Servers

A SLB in Route Mode Routes between Outside and Inside Subnets

A SLB in Inline Bridge Mode Bridges Between VLAN in a Single Subnet

A SLB in one armed mode isn’t inline with the Traffic

Traffic Flow with Misconfiguration

Traffic Flows Correctly when the One-Arm SLB is configured with Client NAT

Using one Firewall per ISP

IGMPv3: Joining a Group

IGMP and CGMP inform Network Devices about Which host want which Multicast data

Multicast Distribution Tree are created by Routers

Source Distribution Tree for Source 1

Separate Source Tree is build for Source 2 sending to the Group

Sources send toward the RP and the RP Sends to the Receivers

PIM-SM Shared Tree Join

PIM-SM Sender Registration Process

PIM-SM Source Tree Switchover

Bidir-PIM is Efficient for Many to many Communication
