Chris,
 
 I have wondered the same thing lately. I have found that as long as the
rest of my routers have the route to the VLAN installed, I can ping the ip
on the switch without having to add "ip default-gateway", ip routing, or
anything else to it. So full connectivity is being reached, but I am
wondering if I should be adding "ip default-gateway" or anything extra to
the switch.

 Thanks,
  Mike

Please could I ask for some opinions.......

A lot of practice lab scenarios state standard assumptions such as "do not
use static or default routes on any router, etc" and "full connectivity must
be attained, etc". Suppose we met this in the real lab, my question is
this... if one of the switches has a vlan interface with an ip address
assigned to it then I assume the pod should be able to ping it and
vica-versa. If the switch is not running an IGP, is the use of "ip
default-gateway" permissible or does this break the rules?

If you can't use "ip default-gateway" do you think configuring irdp on the
attached router in the switch's management vlan would be a good alternative?

thx in anticipation,

Chris.
