Hi all,
I read a few times ago a document on the summarization of external routes within EIGRP.
Here's the content :
EIGRP Autosummarization rules when working with external routes (EX) :
1.If an external route and one (or more) "normal" route are in the same major IP networks as the summary route, the external route is not advertised and only the summary routes is advertised.
2.If there are only external routes that make the summary route, no route at all are advertised (NOT even the summary route !!).
Example case 1 : 11.1.1.0/24 is an external route (via redistribute command) and 11.1.2.0/24 is a direcly connected network. In that case, the router advertised only the summary.
router eigrp 1
redistribute connected route-map test
auto-summary
network 11.0.0.0
Example case 2 : 11.1.1.0 and 11.1.2.0 are external route. In that case, no routes are advertised.
router eigrp 1
redistribute connected route-map test
auto-summary
network 11.0.0.0
I tested this configuration.
In both case, I received the the summary route wich means that the second rule is false.
Can you confirm, please ?
Bye
