You try to create a VLAN that is automatically propagated out to all other switches. The switch allows you to create the VLAN, but it is not propagated to other switches. You execute the show vtp status command (shown below). What is wrong?
Switch> show vtp status VTP Version : 2 Configuration Revision : 0 Maximum VLANs supported locally: 250 Number of existing VLANs : 15 VTP Operating Mode : Transparent VTP Domain Name : VTP Pruning Mode : Disabled VTP V2 Mode : Disabled VTP Traps Generation : Disabled MD5 digest : 0xBF 0x84 0x94 0x33 0xFC 0xAF 0xB5 0x70 Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00 |
You must change the VTP mode to Server before any VLAN information is sent out to other switches.

You need to assign an IP address on a router for a new Ethernet network. You need to assign the router to the first IP address on the second useable subnet taken from the major Class C network of 192.168.25.0/24. The subnet must support at least 13 hosts on each subnet, but you must allow for as many subnets as possible. In addition, the router has been configured with the ip subnet-zero command. Given these requirements, what address would you assign on the router?
