Your summery statements go on your boundry routers (R6) You will then see a
route to null0 on R6 for that summery address. Also, Just a design
question.. Where is area 0?
(R5)---->OSPF AREA 44<----(R6)---->EIGRP<----(R8)

Subject: OSPF NSSA Summary route
OSPF -- R5 -- OSPF(NSSA) -- R6 -- EIGRP -- R8
I have "summary-address 11.0.0.0 255.0.0.0" configured in R5. My question
is: Should "O N1 11.0.0.0/8 [110/21] via 11.1.1.5," appear in R6. The
scenerio answer said "yes", but my router R6 doesn't have this route? Why?
In R5:
11.0.0.0/8 is variably subnetted, 5 subnets, 2 masks
O N1 11.3.0.0/16 [110/21] via 11.1.1.6, 00:07:49, FastEthernet0/0
O N1 11.2.0.0/16 [110/21] via 11.1.1.6, 00:07:49, FastEthernet0/0
C 11.1.0.0/16 is directly connected, FastEthernet0/0
O 11.0.0.0/8 is a summary, 00:07:49, Null0
O N1 11.4.0.0/16 [110/21] via 11.1.1.6, 00:07:50, FastEthernet0/0
O*E2 0.0.0.0/0 [110/1] via 10.10.1.1, 00:07:50, Serial5/0
In R6:
11.0.0.0/16 is subnetted, 4 subnets
D 11.3.0.0 [90/40005120] via 11.2.1.2, 21:32:14, FastEthernet3/0
C 11.2.0.0 is directly connected, FastEthernet3/0
C 11.1.0.0 is directly connected, FastEthernet0/0
D 11.4.0.0 [90/40130560] via 11.2.1.2, 21:32:14, FastEthernet3/0
O*N2 0.0.0.0/0 [110/20] via 11.1.1.5, 00:25:29, FastEthernet0/0
In R8:
C 11.3.0.0 is directly connected, FastEthernet0/0
C 11.2.0.0 is directly connected, FastEthernet1/0
D EX 11.1.0.0 [170/309760] via 11.2.1.1, 21:29:26, FastEthernet1/0
C 11.4.0.0 is directly connected, Loopback0
D*EX 0.0.0.0/0 [170/309760] via 11.2.1.1, 20:44:42, FastEthernet1/0
