Which two statements are true about EIGRP manual summarization? (Choose two.)
A.
Manual summarization is configured on a per interface basis.
B.
Manual summaries can be configured with the classful mask only.
C.
When manual summarization is configured, autosummarization is automatically disabled by
default.
D.
The summary address is assigned an administrative distance of 10 by default.
E.
The summary address is entered into the routing table and is shown to be sourced from the
Null0 interface.
Explanation:
You can configure a summary addresses on a per-interface basis. You need to manually define
summary addresses if you want to create summary addresses that do not occur at a network
number boundary or if you want to use summary addresses on a ASA with automatic route
summarization disabled. If any more specific routes are in the routing table, EIGRP will advertise
the summary address out the interface with a metric equal to the minimum of all more specific
routes.
