Enhanced Interior Gateway Routing Protocol or EIGRP is Cisco's proprietary Distance Vector
routing protocol that replaced the earlier IGRP routing protocol. EIGRP introduced significant
improvements to the IGRP routing protocol including su
Why use Static Routing?
Static routes are not advertised over the network, resulting in better
Static routes use less bandwidth than dynamic routing protocols, no CPU
cycles are used to calculate and communicate routes.
PPP - Point-to-Point Protocol
Key Concept: PPP is a complete link layer protocol suite for devices using TCP/IP, which provides
framing, encapsulation, authentication, quality monitoring and other features to enable robust
operation of TCP/IP over a varie
Today most organization's computer networks need to stretch beyond the simple local area
network. Businesses need to support multiple branches, offices, and remote workers, they need
secure data connections, and continuous data connectivity f
Vlan Trunk Configuration
Assign the out-going interface as a turnk line for the host vlans to travel through:
(config-if)#switchport mode trunk
To Assign the native vlan to this trunk
ACL's Access Control Lists
Standard Access Lists - ACL
Access lists are used as a form of firewall security on a router. Access lists are statements
that a router will use to check traffic against, and if there is a match, the router can filter
Spanning Tree Protocol (STP)
Characteristics of the Spanning Tree Protocols
These are characteristics of the various spanning tree protocols. The italicized words indicate
whether the particular spanning tree protocol is Cisco-proprietary or an IEEE stand
Cloud Frame-Relay Config_PT
Frame Relay is a WAN protocol. A Frame Relay network is comprised of interconnected switches
that make up a Frame Relay cloud. Frame Relay uses virtual circuits (PVC) to interconnect routers
across the WAN.
PPP Authentication (PAP/CHAP)
We will configure PAP on the serial link between R1 and R2.
In our example network, all addressing is done and the correct staic routes have been assigned
on the routers, the is full connectivity and we can pi
*(These are also the basic configuration commands used for IGRP,EIGRP, and OSPF.
To see options and configure things such as.
Port Aggregation Protocols
EtherChannels can be formed through negotiation using one of two protocols, PAgP or
LACP. These protocols allow ports with similar characteristics to form a channel through
dynamic negotiation with adjoining switche
Configuring Frame-Relay with Sub-Divided Interfaces
We will sub-divide each router interface on our network in order to be able to have our Frame
Relay network to function with routing updates, while also still be employing the split-horizon
Configuring Port Security on a Switch
Enabling port security
# interface range fastethernet 0/1-2
Enable port-securty on the port
Set the maximum number of devices that can access the the port/s
#switchport port-security maximum
Shortest Path First Protocols
Just like RIP and EIGRP, basic OSPF operations can be configured using the:
#router ospf process-id global configuration command
#network command to advertise networks
Routers on a Multicast- network elect a
Frame Relay Static Map
Configuring Frame Relay with Static Connections (Static Mapping)
Now that we have a simulated Frame Relay ISP, lets configure Frame Relay on our routers.
Refer again to the example topology.
Let's finish our router configurations, i
The First Hop Rdundancy Protocols
The following list defines the options available for First Hop Redundancy Protocols (FHRPs), as
shown in the figure.
Hot Standby Router Protocol (HSRP) - A Cisco-proprietary FHRP designed to allow for
Extended access lists offer greater flexibility than standard access list due to the fact that you can
filter, not only source IP addresses, but also destination IP addresses, as well as other protocols
ports and services, like TCP
A named access list can be either a standard or extended access list, with the only difference
being that it is identified by name rather than by number. The IOS command for starting a
named access list is slightly different than a nu
