- [Instructor] Dynamic Host Configuration Protocol…dynamically assigns IP addresses…on a local area network.…A Cisco IP phone needs the DHCP server…to provide an IP address.…Special DHCP option 150 is used to send…the unified communications manager's address…to the VoIP devices so they can register…and receive configuration information.…
A router can act as the DHCP server…for its location.…And you'll most likely separate the voice…and data networks so you'll need…to use two DHCP pools.…I've opened a packet tracer file to show how…the commands are used to set up the DHCP pools…on a router.…Now these commands are pretty straightforward.…Let's get into configure your terminal.…
And we'll start with creating…the DHCP pool named voice.…Put in the network address.…And we'll put in the default router's IP address.…
And now we'll create a DHCP pool named data.…And again, we'll put the default…router's IP address.…And then we'll put the special option.…
And then we can exit.…Special option 150 is only required…on a voice VLAN.…
