Darryl,
For RIP, another solution is to send "default-information originate" from
the downstream router.
For IGRP, I think the only way is static. I hope an expert answers this
question on Groupstudy. If you face this in real world, use static. IGRP
is being removed from the Lab this fall, so not really important to find
another method.
HTH, Kym
