Hey Scott,
Thanks for your response. I appreciate it.
I can easily imagine myself forgetting to config a default gateway if it's
not explicitly stated and then losing all the points for dhcp.
Regarding checking and verifying DHCP, I meant is there a way to see if that
a dhcp server is running on the router and how the router believes dhcp is
configured? I know I can do a show run to see what I typed in but beyond
that how I can tell if dhcp is mis-configured when there aren't any actual
dhcp clients. Without actual clients, the dhcp bindings db is empty and
there aren't any dhcp stats to see.
thanks again
