VTP configuration of Cisco Packer Trace

VTP understands:

In a switched network with multiple switches, the same VLAN is typically configured on multiple switches, and the same configuration is made for multiple interfaces. For the need to do the same configuration of multiple interfaces, through the fast interface configuration, can be easily implemented, improve productivity. For the same VLAN configuration on multiple switches, it is implemented via VTP.

VTP in order to configure the same VLAN on multiple switches, through the VLAN of one switch to the other switch propagation method to complete, the other switch after receiving VLAN information, and then update their own VLAN database to achieve synchronization.

To send their VLAN information to the network, the switch must be configured with both Trunk,ieee 802.1Q and ISL support, and the switch connected through the trunk can receive VLAN information from the other side. VTP manages the switches in the network through the domain, and the VLAN information emitted by any switch can only be propagated within one domain, and only switches of the same domain can receive this VLAN information and update their own VLAN database based on the VLAN information received. Whether the switch is in the same domain is distinguished by a domain name, such as the domain name CCIE and the domain name CCIE belong to the same domain, and the domain name CCIE and the domain name Cisco belong to a different domain. The domain name of the default switch is empty, but the most important thing to remember is that if your own domain is empty, then it is the same as any non-empty domain name, that is, if the other party has a domain name, but no domain name, then he and the other belong to the same domain.

The experimental environment is as follows:

Purpose of implementation:

1. Configure the VTP Server on the CORESW core three-layer switch and create the VLAN2 \ VLAN3 and assign IP segments: 192.168.2.0 \ 192.168.3.0.

2. Configure the VTP CLIENT on the SW1 and SW2 switches and divide the port F0/3 of each switch into VLAN2 and F0/4 into VLAN3.

3. Set the IP addresses of each PC as follows:

PC0:192.168.2.2/24 Gateway: 192.168.2.1

PC1:192.168.3.2/24 Gateway: 192.168.3.1

PC2:192.168.2.3/24 Gateway: 192.168.2.1

PC3:192.168.3.3/24 Gateway: 192.168.3.1

4, enable the routing function on the CORESW switch, and configure the routing Exchange protocol, so that the data of each VLAN interoperability.

5. Test whether the data between each VLAN is interoperable.

Experimental steps: (Follow the steps to achieve the goal)

1. Configure the VTP Server on the CORESW core three-layer switch and create the VLAN2 \ VLAN3 and assign IP segments: 192.168.2.0 \ 192.168.3.0.

Question: If I add a host in SW1 or SW2, set the IP address to 192.168.2.5, this main opportunity to ping the VLAN3 host, the result is not, and on the same switch VLAN2 host 192.168.2.2 also ping does not pass.
