Configuring VTP Pruning on a Set/Clear CLI Switch

Enabling pruning on a VTP server enables pruning for the entire domain, which is by default VLANs 2 through 1005. VLAN 1 can never prune.

Before you can set a VLAN to be eligible for VTP pruning, you should go to the switch to see what the available syntaxes are for the command:

5002> (enable) set vtp pruneeligible ?

Usage: set vtp [domain <name>] [mode <mode>] [passwd <passwd>] [pruning <enabledisable>] [v2 <enabledisable>

(mode = clientservertransparent Use passwd '0’ to clear vtp password) Usage: set vtp pruneeligible <vlans>

(vlans = 2..1000 An example of vlans is 2−10,1000)

Now, let’s set VLAN 2 to become eligible for VTP pruning so switches that do not use VLAN 2 will not receive VLAN 2’s broadcast traffic on their trunk links:

5002> (enable) set vtp pruneeligible 2

Vlans 2−1000 eligible for pruning on this device. VTP domain Coriolis modified.

Disabling Pruning for Unwanted VLANs

To disable pruning for VLANs that are not used or that you do not wish to prune, use the following command:

5002> (enable) clear vtp pruneeligible 3−1005 Vlans 1,3−1005 will not be pruned on this device. VTP domain Globalnet modified.

5002> (enable)

Configuring IP InterVLAN Routing on an External Cisco Router

In order to understand this section, you should be familiar with Cisco IOS software running on Cisco routers. In this demonstration, we will configure a Cisco 7505:

1.To enable IP routing on the router, enter Global Configuration mode and use the ip routing command:

7505#configure terminal

Enter configuration commands, one per line. End with CNTL/Z. 7505 (config)#ip routing
