Re: Starve off EIGRP updates?

How important is convergence times? Humm ... a redesign huh? Sounds like
fun!

I do not know the answer to how much bandwidth is needed, i suppose it
depends on the size of your routing tables.

I might suggest to leave the EIGRP bandwidth as is, and instead research and
lab up EIGRP stub and using default / summary routes.

Just a thought, sorry if this does not directly answer your question.

Have a great weekend!
