VTP and VTP Pruning

VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates the definition of Virtual Local Area Networks (VLAN) on the whole local area network. To do this, VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over 802.1Q, and ISL trunks.

Three VLAN division with three broadcast domain

VTP pruning is a feature in cisco switches, which stops VLAN updates information traffic from being sent down trunk links if the updates are not needed. VLAN 1 can never be prune because it’s an administrative VLAN.

VTP Pruning

VTP-SERVER

Switch1(config)#vtp domain VtpDomain
Switch1(config)#vtp password VtpPassword
Switch1(config)#vtp pruning

VTP-CLIENT

Switch2(config)#vtp mode client
Switch2(config)#vtp domain VtpDomain
Switch2(config)#vtp password VtpPassword

VTP-TRANSPARENT

Switch3(config)#vtp mode transparent
Switch3(config)#vtp domain VtpDomain
Switch3(config)#vtp password VtpPassword

VERIFICATION

Switch2(config)#show vtp status

Subnetting

Image
Learning subnetting is much easier that it looks. All you need is basic understanding of  IP Addressing and Maths Formulas Of Subnetting 1. Number of Valid Host (2n-2) Where n is number of Host bits (0's) 2. Number of Valid Network (2y) Where y is number of borrowed Network bits   (1's) NOTE : With ip-subnet command we can use 1st & last ip NOTE : Block size remain same for all classes Learn the following table or save it for solving subnetting much faster.   Wild Card is always 1 less then block size. Example : \30 Wildcard will be (Block size -1) (4-1) =3 \30= 0.0.0.3
