Cisco router basic
1. ROUTING
1. Routing is the method by which network devices direct messages across
networks to arrive at the correct destination.
2. All routers must have routing decisions.
3. They do this by looking ip information stored in their routing tables.
4. Every router contains a table of all locally-connected networks and the interfaces
that connected to them
5. Routing table also contain information about the routes, or paths, that the router
uses to reach other remote networks that are not locally attached.
6. A route has four main components
• Destination Value
• Mask
• Gateway or interface address
• Route cost or metric
7. To direct a message to the correct destination, the router looks at the destination IP
address in the packet and then looks for a matching route in the routing table.
8. The destination values in a routing table refer to destination network address.
2. FUNCTION OF ROUTERS
1. A router is networking device that connects a local network to other local networks.
2. The routers reads the network portion of the destination IP address and uses it to find
which one of the attached networks is the best way to forward the message to the
destination.
3. Routers encode and also decode the packet that is encapsulated within the frame.
4. Each port or interface on a router connects to a different local network.
5. Every router contains a table of all locally-connected networks and the interfaces that
connect to them. These routing tables can also contain information about the routers, or
paths, that the router uses to reach other remote networks that are not locally attached
6. Router maintains two tables i.e ARP and ROUTING table.
3. Routing types:-
MANUALLY:-Remote networks are manually entered into the route table using static
routes.
DYNAMICALLY:-remote routes are automatically learned using dynamic routing
protocol.

26. In static routing , we are manually adding the destination network to our routing table.
There are four types of IPv4 and IPv6 static routes.
STANDARD STATIC ROUTE
DEFAULT STATIC ROUTE
SUMMARY STATIC ROUTE
FLOATING STATIC ROUTE
Router (config)# ip route <destination N/w> <DSNM> <exit interface>
Example :-
Router (config)# ip route 30.0.0.0 255.0.0.0 20.0.0.2 (standard static route)
Router (config)# ip route 0.0.0.0 0.0.0.0 172.16.2.2 (default static route)
27. DYNAMIC ROUTING
There are two types of dynamic routing protocol
are used for routing:
1. DISTANCE VECTOR PROTOCOL (RIP,IGRP,EIGRP)
Identifies how far it is to the destination network and is based
on a metric such as the hop count,cost,bandwidth,delay.
2. LINK STATE PROTOCOL (OSPF,IS-IS)
Specifies the direction of the next-hop router or exit interface to
reach the destination.
3. BORDER GATEWAY PROTOCOL (BGP)
Path vector routing protocol.
28. RIP (ROUTING INFORMATION PROTOCOL)
1. To enable RIP routing for a network,use the network
network-address router configuration mode command.
2. Advertises the specified network in RIP routing updates
sent to their routers every 30 seconds.hold down time 180
secs,flushed after 240 secs.
3. Choose best path based on hop count ( max hop count -15).
RIP V1 RIP V2
Support VLSM NO YES
Support CIDR NO YES
Support Summarization NO YES
Support Authentication NO YES
Updates forward to Address 255.255.255.255 224.0.0.9
Maximum hop count 15 15
29. ROUTER 1
R1(config)# router RIP
R1(config-router)# version 2
R1(config-router)# network 192.168.1.0
R1(config-router)# network 192.168.3.0
R1(config-router)# no auto-summary
ROUTER 2
R1(config)# router RIP
R1(config-router)# version 2
R1(config-router)# network 192.168.2.0
R1(config-router)# network 192.168.3.0
R1(config-router)# no auto-summary
192.168.3.0
192.168.1.0 192.168.2.0
30. EIGRP(Enhanced Gateway Routing Protocol)
It is an advanced distance vector routing protocol developed by cisco systems.
1. Supports to classless Address
2. Resources uses medium.
3. Scalability large
4. Speed high
Types of EIGRP Packets:-
Hello Packets :- To discover routers
Updates Packets :- Convey routing information.
Acknowledge Packets :-Acknowledge the receipt of packets.
Query Packets :- Used to query routes from neighbors.
Reply Packets:- send in response to an EIGRP query.
Command for EIGRP :-
Router(config)# router eigrp autonomous-system
The autonomous-system between the number 1 and 65,535.
All routers within the EIGRP routing domain must use the same autonomous system
number.
32. OSPF(Open Shortest Path First)
OSPF features includes:-
Classless:- It is classless by design, therefore it supports VLSM
and CIDR.
Efficient :- it uses the SPF algorithm to choose the best path.
Fast Convergence :- It quickly propagates network changes.
Scalable :- It works well in small and large network sizes. Routers
can be grouped into areas to support a hierarchical system.
Secure :- OSPF routers only accept encrypted routing updates
from the peers with the same pre-shared password.
OSPF creates and maintain three databases :-
Adjacent databases – Create the neighbour table.
Link-state database (LSDB)-Create the topology table.
Forwarding database:- Create the routing table.
33. Routing Protocol Messages :-
OSPF exchanges messages to convey routing information using five types of
packets.
Hello packets
Database description packet
Link-state request packet
Link-state update packet
Link-state acknowledge packet
An OSPF area is a group of routers that share the same link-state information in
their LSDBs.
Single-Area OSPF – all routers are in one area called the backbone area (area 0)
Multiarea OSPF – OSPF is implemented using multiple areas, in a hierarchal
fashion. All areas must connect to the backbone area ( area 0).Routers
interconnecting the area referred to as Area Border Routers (ABR).
40. Configuring Port Security on an Interface
To restrict traffic through a port by limiting and identifying MAC addresses of the stations allowed to access the
port, perform this task:
Command Purpose
Step 1 Switch(config)#
interface
interface_id
Enters interface configuration mode and enters
the physical interface to configure, for
example gigabitethernet 3/1.
Step 2 Switch(config-if)#
switchport mode
access
Sets the interface mode as access; an interface in
the default mode (dynamic desirable) cannot be
configured as a secure port.
Step 3 Switch(config-if)#
switchport port-
security
Enables port security on the interface.
Step 4 Switch(config-if)#
switchport port-
security maximum
value
(Optional) Sets the maximum number of secure
MAC addresses for the interface. The range is 1 to
3072; the default is 1.
41. Step 5 Switch(config-if)#
switchport port-
security violation
{restrict |
shutdown}
(Optional) Sets the violation mode, the action to
be taken when a security violation is detected, as
one of these:
•restrict—A port security violation restricts data
and causes the Security Violation counter to
increment and send an SNMP trap notification.
•shutdown—The interface is error-disabled when
a security violation occurs.
Note When a secure port is in the error-disabled
state, you can bring it out of this state by entering
the errdisable recovery cause psecure-
violation global configuration command or you
can manually reenable it by entering
the shutdown and no shut down interface
configuration commands.
Step 6 Switch(config-if)#
switchport port-
security limit rate
invalid-source-mac
Sets the rate limit for bad packets.
42. Step 7 Switch(config-if)#
switchport port-
security mac-
address
mac_address
(Optional) Enters a secure MAC address for the
interface. You can use this command to enter the
maximum number of secure MAC addresses. If
you configure fewer secure MAC addresses than
the maximum, the remaining MAC addresses are
dynamically learned.
Step 8 Switch(config-if)#
switchport port-
security mac-
address sticky
(Optional) Enable sticky learning on the interface.
Step 9 Switch(config-if)#
end
Returns to privileged EXEC mode.
Step 10 Switch# show
port-security
address
interface
interface_id
Switch# show
port-security
address
Verifies your entries.
