Re: Eigrp summary-route

Hey Brian ,

What you are saying is absolutely correct and what Nayyar is saying also
correct .
Checkout both scenarios are different .

+) You are summarizing a network which is already in EIGRP topology .
+) Anantha was summarizing a network which is not in the EIGRP topology (its
Loopback interface address).

What i beleive is that for any Routing protocol summarization will only work
when it finds the network in its routing protocol database .
