[c-nsp] cisco ios dhcp server

[Fields, Jesse]

Yes, the router should act as a fully functional DHCP server.  You just need to setup the pools for the remote networks and ip helper the requests to it.

>From the Cisco docs -- "The Cisco IOS DHCP server can accept broadcasts from locally attached LAN segments or from DHCP requests that have been forwarded by other DHCP relay agents within the network."

There are some advanced options available if you want to get fancy. =)

This explains it better than I:  http://www.cisco.com/en/US/docs/ios/ipaddr/configuration/guide/iad_dhcp_svr_cfg.html#wp1122709

I hope this is what you were looking for.

No, I'm familiar with those commands, thats what I would use on a
remote Cisco router to forward the DHCP requests up to a central DHCP
server.

My question is, can the IOS DHCP server respond to requests relayed to
it by another router?
