The document discusses several routing protocols used in TCP/IP networks, including RIP, OSPF, and BGP. It begins by distinguishing between intra-domain routing within an autonomous system and inter-domain routing between autonomous systems. It then covers the distance vector routing protocol RIP, the link state routing protocol OSPF used for intra-domain routing, and the path vector routing protocol BGP used for inter-domain routing. For each it discusses the routing algorithm, packet formats, and other implementation details.
Overview of IP routing protocols, packet forwarding and proxy ARP.
The principle of IP routing proved to be very flexible and scalable in the growth of the Internet and TCP/IP based networks.
IP routing denotes protocols for exchanging IP address range reachability like RIP, BGP and OSPF.
In contrast to IP routing, IP packet forwarding collectively means all functions performed when an IP router receives a packet and forwards it over the output interface indicated by an IP route in the routing table.
When an IP router performs a route lookup, it calculates a route decision based on different properties like prefix (mask) length, route precedence and metrics.
Routing protocols for exchanging route information can be coarsely classified as distance vector and link state protocols. Distance vector protocols like RIP (Routing Information Protocol) exchange information about the path cost to specific targets (IP address ranges). Routers that talk distance vector protocols receive reachability information about all sub-networks indirectly from neighboring routers.
In contrast to distance vector protocols, link state protocols like OSPF disseminate information about the link state of each router link in a network to all routers in the network. Thus link state protocols tend to converge faster to topology changes since all routers have firsthand information of the topology of the network.
Proxy ARP may be a convenient solution when it comes to add additional subnets without having to add routes to routers and hosts. A proxy ARP enabled router would answer ARP requests on behalf of the targeted hosts mimicking a local network access to the requesting host.

Overview of RARP, BOOTP, DHCP and PXE protocols for dynamic IP address assignment.
Dynamic IP address assignment to a host (or interface) is a common problem in TCP/IP based networks.
Manual and static assignment of IP addresses does not scale well and becomes a labor intensive task with a growing number of hosts.
An early approach for dynamic IP address assignment was RARP (Reverse ARP) which ran directly on the Ethernet protocol layer.
The many problems of RARP such as the inability to be routed between subnets were solved with BOOTP (Bootstrap Protocol).
BOOTP, however, ended to have its own set of limitations like lack of a lease time for IP addresses.
DHCP (Dynamic Host Configuration Protocol) was therefore defined as an extension to BOOTP.
DHCP is backward compatible with BOOTP thus allowing some degree of interoperability between the 2 protocols.
The state-of-the-art protocol for dynamic IP address assignment is, however, is DHCP.
DHCPv6 is an adaption of DHCP for IPv6 based networks.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

Objectives
2. TCP/IP Protocol Suite 2
14.1 INTRA- AND INTERDOMAIN
ROUTING
Routing inside an autonomous system is referred to as intradomain
routing. Routing between autonomous systems is referred to as
interdomain routing.
5. TCP/IP Protocol Suite 5
14.2 DISTANCE VECTOR ROUTING
In distance vector routing, the least cost route between any two nodes is
the route with minimum distance. In this protocol each node maintains a
vector (table) of minimum distances to every node
The topics discussed in this section include:
Initialization
Sharing
Updating
When to Share
Two-Node Loop Instability
Three-Node Instability
7. TCP/IP Protocol Suite 7
Figure 14.4 Initialization of tables in distance vector routing
8. TCP/IP Protocol Suite 8
In distance vector routing, each node
shares its routing table with its
immediate neighbors periodically and
when there is a change.
Note:
12. TCP/IP Protocol Suite 12
14.3 RIP
The Routing Information Protocol (RIP) is an intradomain routing
protocol used inside an autonomous system. It is a very simple protocol
based on distance vector routing.
The topics discussed in this section include:
RIP Message Format
Requests and Responses
Timers in RIP
RIP Version 2
Encapsulation
16. TCP/IP Protocol Suite 16
Figure 14.11 shows the update message sent from router R1 to
router R2 in Figure 14.8. The message is sent out of interface
130.10.0.2.
Example 1
See Next Slide
The message is prepared with the combination of split horizon
and poison reverse strategy in mind. Router R1 has obtained
information about networks 195.2.4.0, 195.2.5.0, and 195.2.6.0
from router R2. When R1 sends an update message to R2, it
replaces the actual value of the hop counts for these three
networks with 16 (infinity) to prevent any confusion for R2.
The figure also shows the table extracted from the message.
Router R2 uses the source address of the IP datagram carrying
the RIP message from R1 (130.10.02) as the next hop address.
19. TCP/IP Protocol Suite 19
A routing table has 20 entries. It does not receive information
about five routes for 200 s. How many timers are running at
this time?
Example 2
Solution
The 21 timers are listed below:
Periodic timer: 1
Expiration timer: 20 − 5 = 15
Garbage collection timer: 5
23. TCP/IP Protocol Suite 23
14.4 LINK STATE ROUTING
In link state routing, if each node in the domain has the entire topology
of the domain, the node can use Dijkstra’s algorithm to build a routing
table.
The topics discussed in this section include:
Building Routing Tables
29. TCP/IP Protocol Suite 29
14.5 OSPF
The Open Shortest Path First (OSPF) protocol is an intradomain routing
protocol based on link state routing. Its domain is also an autonomous
system.
The topics discussed in this section include:
Areas
Metric
Types of Links

Give the router link LSA sent by router 10.24.7.9 in
Figure 14.31.
Example 3
Solution
This router has three links: two of type 1 (point-to-
point) and one of type 3 (stub network). Figure 14.32
shows the router link LSA.
See Next Slide
See Figure 14.32
51. TCP/IP Protocol Suite 51
In Figure 14.37, which router(s) sends out router link LSAs?
Example 5
Solution
All routers advertise router link LSAs.
a. R1 has two links, N1 and N2.
b. R2 has one link, N1.
c. R3 has two links, N2 and N3.
See Next Slide
53. TCP/IP Protocol Suite 53
In Figure 14.37, which router(s) sends out the network link
LSAs?
Example 6
Solution
All three network must advertise network links:
a. Advertisement for N1 is done by R1 because it is the only
attached router and therefore the designated router.
b. Advertisement for N2 can be done by either R1, R2, or R3,
depending on which one is chosen as the designated router.
c. Advertisement for N3 is done by R3 because it is the only
attached router and therefore the designated router.
65. TCP/IP Protocol Suite 65
14.6 PATH VECTOR ROUTING
Path vector routing is similar to distance vector routing. There is at least
one node, called the speaker node, in each AS that creates a routing table
and advertises it to speaker nodes in the neighboring ASs..
The topics discussed in this section include:
Initialization
Sharing
Updating
68. TCP/IP Protocol Suite 68

Border Gateway Protocol (BGP) is an interdomain routing protocol

four versions.
