Little question about EIGRP summary address

Hello Group,

It4s necessary to configure a component of a summary route under the EIGRP
proccess to announce the summary address ?, or it is just enough having a
component of the sumary route in the routing table ?

i.e.

R1 s0/0-------------------------------- s0/0 R2 .2 -------10.0.0.0/24 lan
segment
.1 1.1.1.0/24 network .2

R2 config:

interface s0/0
 ip address 1.1.1.2 255.255.255.0
 ip summary-address eigrp 10 10.0.0.0 255.0.0.0
!
router eigrp 10
 network 1.1.1.2 0.0.0.0
 network 10.0.0.2 0.0.0.0 --> Do I need to add this to my config if I want R2
to announce the summary route ??
!

Is this enough so R2 announces 10.0.0.0/8 network to R1,

or do I need to configure a component of the 10.0.0.0/8 network unter the
EIGRP 10 proccess ??

TIA
Julio
