Hello..
Here we can create some alias command also in cisco routers.
Router(config)#alias configure jignesh router ospf 1
then just type command alias name "jignesh"
Router(config)#jignesh
see what happen "router ospf 1" is is fired on your router.
Thanks

Static Routing and Default Routing.
Hello Boys & Girls..
In normally CCNA we learn lots of theory regarding routing types static and dynamic but actually where static routing is really used no one tell you, most of times it is used in customer premises equipments. like I give some brief example
R1(config)#ip route 0.0.0.0 0.0.0.0 s3/0
called Default static routing
IPS(config)#ip route 192.168.20.0 255.255.255.252 s0
IPS(config)#ip route 10.10.10.0 255.255.255.252 s0
As you see here IPS can't create default route cause on IPS router more than one customer are connected so IPS router manually specified or introduce your all network in their network that you have to care about that. one more thing after static routing it will be redistribute with IPS routing method so as Customer you don't need to very that ISP's responsibilities to introduce their network wholeover
Thank you,

Subnetting Logic
Hello All.
We are know very well subnet means a huge network divided into many sub networks.
so we take small example therefore we easily understand.
Example: company ABC have it's own network id: 220.220.21.0/24. Administrator want to divided into network 8 sub networks.
Answer: There are THREE Easy Step 1 2 3.
Step 1: Here total 8 networks means power(2)n where n is number of bits borrowed from host portions.so total 3 bit cause power(2)3 = 8.Basis on that we find subnet mask for networks is 255.255.255.224. How na? (easy 24 bit + 3 bit borrow so total /27).
Step 2: Calculate Block Size is also easy: last octant is minus from 256.
Block Size = 256 - last octant. (256-224 = 32)
Step 3: So finally we find block size is 32.
we create sub networks easily 0, 32, 64, 96, 128, 160, 192, 224, 256 ohh... wait...
256 it's over. we get first 8 network ids.
minus one from next network id we get broadcast address of current networks like 31, 63, 96, 127, 159, 191, 223, 255.
Between these range are usable IP address in networks.

Assing IP to Switch and Make Remote Connection
Hi All..
How to assign IP to switch for remote operating?
We all know that switch is operate at 2 layer but still we assign IP to switch and
make remote connection to switch. In switch by default VLAN1 is native so at a time we activate one vlan1 and all ports by default members of native vlan.
Switch(config)#vlan 1
Switch(config-if)#ip address 192.168.1.1 255.255.255.0
Switch(config-if)#exit
Switch(config)#exit
------------------------Remote Side-----------------------------------------------
C:>telnet 192.168.1.1

Basic Commad Is used to run SDM on router
Hello All.
Here I show very basic command to run SDM (Security Device Manager) to run on router.
Before running SDM commands on router first you need basic knowledge of router IOS version is it supported or not.
http://www.cisco.com/en/US/products/sw/secursw/ps5318/
Now Following Basic Commands
Router(config)#ip http server
Router(config)#ip http secure-server (Optional if u configure https on port 443)
Router(config)#username cisco privilaged 15 passwrod cisco
Router(config)#ip http authentication local
Router(config)#crypto key generate rsa general keys modulus 1024
Router(config)line vty 0 871
Router(config-line)#login local
Router(config-line)#transport input telnet
Router(config-line)#transport input telnet ssh
Router(config-line)#end
---------------just launch SDM and put IP address----------------
Note JAVA Runtime or JVM must be install on your system and pop blocker must be disable.
