The following is another example of a VLAN (110) on a router. This one has the ip helper-address (DHCP server) specified for this range.
description “Ak IDN”
encapsulation dot1Q 110
ip address 172.25.20.1 255.255.255.0
ip helper-address 172.25.20.15
That is the router side of things setup. Remember to save your changes via…
copy run start
Now you’ll need to add the VLAN to your switches. If you have VTP in your environment its as simple as adding the extra vlan onto your “server” vtp switch. Telnet (or null cable) to your “server” switch and go into “enable” mode, then go into the vlan database and add the required vlans as per above…
vlan 2 name “VM Host Network”
vlan 110 name “Ak IDN”
VTP will propagate the vlans out to your client switches. Done.
