3.  Explain the role of VTP in a converged switched network.
 Describe VTP Components:
 Domain, Advertisements and Pruning.
 Describe VTP Modes:
 Server, Client and Transparent.
 Describe VTP Operation:
 Configure VTP on Catalyst switches.

4.  What does VTP stand for?
VLAN Trunk Protocol (VTP).
 is a Cisco-proprietary protocol used to exchange VLAN
information across trunk links.
 allows network manager to distribute VLAN
configurations to all switches in the same domain.
 stores VLAN configurations in VLAN database so, it is
called vlan.dat.
429 / 4 / 2015

5.  It works on layer two (Data link) of OSI model.
 propagates VLAN configurations to other switches in the
same domain.
 reduces the need to configure the same VLAN on each
switch at the network.
 distributes and synchronizes VLAN information to all
VTP-enabled switches in the entire network.

6.  VTP only learns about normal-range VLANs (VLAN IDs
1 to 1005).
 Extended-range VLANs (IDs greater than 1005) are not
supported by VTP.

7.  There are three different components of VTP:
 Domain, Advertisements and Pruning.
729 / 4 / 2015

8.  Consists of one or more interconnected switches sharing
the same VTP domain name.
 All switches in a domain share VLAN configuration details
by using VTP advertisements.
 A router or Layer 3 switch defines the boundary of each
domain.
829 / 4 / 2015

9.  or VTP Messages.
 uses a hierarchy of advertisements to distribute and
synchronize VLAN configurations over trunk links.
 distributes VTP domain name and VLAN configuration
changes to VTP-enabled switches.
929 / 4 / 2015

10.  prevents unnecessary flooding of broadcast information
from one VLAN across all trunks in VTP domain.
 enables pruning on one VTP server switch in one domain.
 is disabled by default.
 is enabled by using the vtp pruning global configuration
command.

12.  VTP have three different modes.
 A switch can be configured in one of three modes:
1229 / 4 / 2015

13.  advertises the VTP domain VLAN information to other
switches in the same VTP domain.
 stores the VLAN information for the entire domain in
NVRAM.
 The VLAN can be created, deleted or renamed for the
domain.
 Every catalyst switch is a server by default.
1329 / 4 / 2015

14.  receives information from VTP server.
 sends and receives updates same as VTP server but
can not create, change and delete VLANs.
 Stores the VLAN information in RAM while the switch is
on.
 A switch reset deletes the VLAN information so, you
must configure VTP client mode on a switch again.
1429 / 4 / 2015

15.  forwards VTP advertisements to VTP clients and VTP
servers.
 does not participate in VTP.
 does not accept VLAN information.
 VLANs that are created, renamed, or deleted on
transparent switch is saved inside that switch only in
NVRAM.

17.  separate the network into smaller network VLAN
management.
 simplify the management of VLAN database across
multiple switches.
 easy VLAN management on switches such as adding,
deleting and renaming VLANS.
 dynamic trunk configuration when the new VLANs are
added.
1729 / 4 / 2015

18.  configurations are consistent and have less errors.
 dynamic report when the new VLANs are added.
 reduce VLAN management.
1829 / 4 / 2015

19.  Incompatible VTP versions.
 VTP password issues.
 Incorrect VTP mode name.
 All switches set to VTP client mode.

20. Challenge game
The maximum time: 5 minutes.
 Divide the trainees in two groups such as group A and group B.
 Group A is to draw VTP components topology diagram and write
VTP components on it to clarify the topology diagram with giving us
short explanation about it.
 Group B is to draw VTP modes topology diagram and write VTP
modes on it to clarify the topology diagram with giving us short
explanation about it.

21.  VTP is a Cisco proprietary protocol used to exchange VLAN
information across trunk links.
 VTP have three different components:
 VTP Domain:
Consists of one or more interconnected switches sharing one domain
name.
 VTP Advertisements or Messages:
Distribute VTP domain name and synchronize VLAN configurations
over trunk links inside one domain.
 VTP pruning:
Limits unnecessary distribution of VLAN information.
2129 / 4 / 2015

22.  A switch can be in one of three VTP operating modes:
 Server: Can create, modify & delete VLAN.
 Client: Cannot create, modify or delete VLAN.
 Transparent: Can create, modify, & delete local VLAN.
Forwards VTP advertisements.
 Verify VTP configuration:
 show VTP status
 show interfaces trunk
