The document describes how to configure Interior Gateway Routing Protocol (IGRP) on three routers to enable connectivity between three networks. It provides the configuration steps for each router, including setting hostnames, IP addresses on interfaces, and enabling IGRP with the network commands. It also shows how to verify the routing tables and connectivity between networks using the ping command.
This document discusses the Exterior Gateway Protocol (EGP), including its origins as a way to scale routing between autonomous systems, how it establishes and maintains neighbor relationships to exchange reachability information, and its limitations that led to the development of the Border Gateway Protocol (BGP).
The document discusses the Interior Gateway Routing Protocol (IGRP) and Enhanced Interior Gateway Routing Protocol (EIGRP). IGRP was developed by Cisco in 1986 as an alternative to RIP routing, which had limitations like metric hop count and routing overhead. IGRP uses a composite metric including bandwidth, delay, reliability, and loading to determine the best path. It supports unequal cost load balancing and converges faster than RIP. EIGRP is an enhanced version of IGRP that uses the same metric system and supports features like variable length subnet masking.
It is an open standard, distance vector, classfull routing protocol. Rip version 2 supports classless.
It sends the complete routing table out to all active interfaces every 30 seconds. Rip only uses hop count
to determine the best way to a remote network, but it has a maximum allowable hop count of 15 by
default, meaning that 16 is deemed unreachable. RIP works well in small networks, but it’s inefficient on
large networks with slow WAN links or on networks with a large number of routers installed.
EIGRP is a cisco proprietary, Advance distance vector, classless Interior gateway routing protocol.
Released in-1994.
It works on Network Layer of OSI Model.
It use the IP protocol no 88. (It doesn’t use TCP or UDP)
EIGRP AD – 90
Eigrp External routes AD – 170
EIGRP has a maximum hop-count of 224, though the default maximum hop-count is set to 100
EIGRP and OSPF are routing protocols. EIGRP uses the DUAL algorithm and metric to select fast, loop-free routes. It supports multiple network layers and rapid convergence. OSPF is an open standard link-state protocol that provides a common network view and calculates the shortest path. It can route between autonomous systems and uses link state updates and SPF algorithm. Configuring OSPF involves assigning networks to areas and defining the routing process. Verification includes checking neighbors, routes, and topology tables.

- Packet Tracer is a program used to illustrate basic network concepts and allow users to build and test networks in real-time.
- A router is a networking device that connects different networks and selects the best path to forward packets between them based on its routing table. Cisco is the leading manufacturer of routers.
- There are different modes that allow administrators to monitor and configure routers, including setup, user, privileged, global configuration, and interface modes. Static and dynamic routing can be configured to determine the best paths between networks.
This document summarizes a chapter about EIGRP and OSPF routing protocols. It discusses key aspects of configuring and verifying EIGRP like using the router eigrp command to enable EIGRP on interfaces, and show commands to view EIGRP neighbor relationships and routing tables. It also covers fundamental OSPF concepts like using network statements to assign interfaces to areas, and show commands to verify the OSPF configuration and neighbor adjacencies. The document provides configuration examples and explains OSPF terminology regarding neighbors, designated routers, and using wildcards in network statements.
RIP is an interior gateway protocol that employs distance-vector routing and uses hop count as its routing metric. It works by periodically sharing full routing tables between neighboring routers to detect changes in network reachability. The maximum number of hops allowed in the RIP protocol is 15, which limits the size of networks it can support. There are two versions of RIP - version 1 lacks support for VLSM and authentication, while version 2 adds these features and multicasts updates. RIP has limitations such as slow convergence, count to infinity problems, and an inability to support networks larger than 15 hops without extensions.
The document discusses configuring EIGRP on routers. EIGRP configuration requires enabling EIGRP using the "router eigrp ASN_NUMBER" command and specifying networks to advertise using the "network SUBNET" command. The ASN number must match across routers to establish neighbor relationships. The network command can use a wildcard mask to enable EIGRP on specific interfaces rather than all interfaces in a classful network. Verification commands like "show ip eigrp neighbors" and "show ip route" are provided to check neighbor relationships and exchanged routes.
EIGRP is an advanced distance-vector routing protocol created by Cisco that uses the Diffusing Update Algorithm (DUAL) to calculate paths and back-up paths. It establishes neighbor adjacencies, uses reliable transport to deliver packets to neighbors, and sends partial and bounded updates only when there is a change.
VRRP (Virtual Router Redundancy Protocol) is a computer networking protocol that provides for
automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the
availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.
The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the
static default routed environment. VRRP specifies an election protocol that dynamically assigns
responsibility for a virtual router (a VPN 3000 Series Concentrator cluster) to one of the VPN
Concentrators on a LAN. The VRRP VPN Concentrator that controls the IP address(es) associated with a
virtual router is called the Master, and forwards packets sent to those IP addresses.
IPV6 uses a 128-bit address with 8 groups of 16 bits each. It does not support broadcast, NAT, or subnetting like IPv4. Communication types include unicast (one-to-one), multicast (one-to-many), and anycast (one-to-nearest). Special IP addresses include the loopback (::1), invalid (::), multicast (ff80::), link-local (fe80::), global unicast (2000::), and unique local (fc00::). WAN connections can be via dedicated lines, packet switching like Frame Relay, or protocols including HDLC, PPP, and Frame Relay which is configured between routers with DLCI, IP
The document discusses the Routing Information Protocol (RIP). It describes that RIP is a distance-vector interior gateway protocol that uses hop count as its routing metric. It discusses the two versions of RIP - RIPv1 and RIPv2, and their differences in areas like classful/classless operation, broadcast/multicast updates. It also covers RIP configuration, operation, timers, authentication, route filtering, and other features.
OSPF is a link-state routing protocol that uses the Shortest Path First algorithm to calculate the shortest path to destinations. It propagates link-state advertisements rather than routing table updates. OSPF supports hierarchical routing to minimize routing updates. Single-area OSPF configurations assign networks to areas using the network command under the OSPF routing process.
ACLs (Access Control Lists) are used to control network traffic through routers by permitting or denying traffic based on conditions like source/destination IP addresses. There are two types: standard ACLs filter based on source IP and are configured on destination routers, while extended ACLs filter on source/destination IP and can block specific protocols. NAT (Network Address Translation) converts private IP addresses to public IP addresses to avoid IP address depletion and implement network security through configurations like static, dynamic, or port address translation which maps private ports to a public IP address.
The document provides an overview of static and dynamic routing concepts, protocols, and configuration. It discusses static and default routing, as well as dynamic routing protocols including RIP, IGRP, EIGRP, OSPF, BGP, and their characteristics. Troubleshooting commands are also listed to verify routing tables and debug routing issues.
The document discusses OSPF internal route summarization. It explains that OSPF summarization can only be configured on area border routers (ABRs) between areas, and that it involves using a route range to join multiple routes into fewer summary routes. Configuring summarization reduces routing table and link state database sizes. The example shows routing tables and link state databases before and after configuring a route range on an ABR to summarize two networks in an area into a single inter-area route.
This document discusses redistributing routes between OSPF and EIGRP routing protocols. There are two types of external routes when redistributing into OSPF - E1 and E2. E1 routes are redistributed with the default metric plus the internal OSPF cost, while E2 routes are redistributed with the default metric unchanged. The example topology redistributes routes between two EIGRP domains into an OSPF domain, marking one set of redistributed routes as E1 and the other as E2. Verification commands are provided to check the redistribution.

The difference between yellow and white labeled ports on a nexus 2300 series fexIT Tech
What is the Difference between Yellow and White Labeled Ports on a Nexus 2300 Series FEX?
The Cisco Nexus 2300 platform provides two types of ports: ports for end-host attachment (host interfaces) and uplink ports (fabric interfaces). Both yellow and white colored fabric interfaces can be used to provide connectivity to the upstream parent Cisco Nexus switch. There is no difference between yellow labeled and white labeled uplink ports.
The Cisco 892F ISRs have an SFP port that supports auto-media-detection, auto-failover, and remote fault indication (RFI), as described in the IEEE 802.3ah specification.
The Nexus 7000 Series switches form the core data center networking fabric. There are multiple chassis options from the Nexus 7000 and Nexus 7700 product family. The Nexus 7000 and the Nexus 7700 switches offer a comprehensive set of features for the data center network.

How to Configure Interior Gateway Routing Protocol (IGRP)?
If you are not familiar with Interior Gateway Routing Protocol (IGRP), click the
following link to view an introduction to Interior Gateway Routing Protocol (IGRP).
Interior Gateway Routing Protocol (IGRP) Configuration
Interior Gateway Routing Protocol (IGRP) can be configured in a router using the
following IOS commands. If you have a new router with a latest IOS release, you may
not find Interior Gateway Routing Protocol (IGRP) configuration commands because
Interior Gateway Routing Protocol (IGRP) is removed from new IOS releases.
Router(config)# router igrp ASN
Router(config-router)# network Network_ID
ASN in the above IOS command stands for Autonomous System Number.
Interior Gateway Routing Protocol (IGRP) - Lab Practice
The following diagram shows our lab setup. We have three routers, three switches
and three hosts connected as below. The host names, IP addresses and the interfaces
of the routers are shown in diagram. The IP addresses of the hosts are also shown in
the diagram.
