I'm just getting into Cisco and am prepping for the CCNA. After reading through the ICND1 and ICND2 Cisco Press books I didn't see anything about DHCP, everything used static IP addresses with static netmasks and default gateways.
Is DHCP covered in the CCNA or is that a CCNP topic?
Is it industry standard to run DHCP servers on routers or to use an external server?
Let's say I'm running a few vlans with a router-on-a-stick configuration to route between them. It would make sense to put the dhcp server on that router, and I suppose in order to give out the proper IP addresses it would have to be manually configured for each sub-interface that is associated with each the vlan. Is that correct?
What if instead of a router-on-a-stick I were using a layer 3 switch, or in a larger network with possibly a few layer 3 switches. In that case where would the dhcp server be located?
Since this topic wasn't covered at all I'm thinking I don't really need to commit it to memory for the test, but it's been bugging me for a while and I wonder about it each time I look at a network diagram in the books.
I'm hoping my question made sense. Thanks.
