Summary-address command is also for inbound redistribution i.e. rip to ospf.

R4
router ospf 1
 router-id 150.5.4.4
 log-adjacency-changes
 area 4 nssa
 summary-address 130.1.0.0 255.255.0.0
 redistribute rip subnets route-map NSSA
 network 150.5.4.4 0.0.0.0 area 4
 network 150.5.40.4 0.0.0.0 area 4
!
ip prefix-list 130 seq 5 permit 130.1.1.0/24
ip prefix-list 130 seq 10 permit 130.1.2.0/24
ip prefix-list 130 seq 15 permit 130.1.3.0/24
route-map NSSA permit 10
 match ip address prefix-list 130
 set metric-type type-1

R3
O N1 130.1.0.0/16 [110/85] via 150.5.40.4, 00:03:33, Serial0.40

hi,

I don't really understand the question either, but the summary command on
ospf is for outbound redistribution only i.e. leaving ospf into rip, and the
router will not advertise a summary route in the ospf domain.

Kinda confused as to what you are asking.. But if u redistributed the
connected route into R1, R1 is going to send the route to R2 as a E1 or
E2 whatever u define it to be. Then R2 is going to send it the RIP
router

Hi all,

Because of topology contraints I have to redistribute
connected on an OSPF route to do summarization. I then
need to summarize the routes and send them into a
RIPv1 domain.

X---R1---W---R2---Y(RIP)

R1's X - is the connected network I need to
redistribute. R2 and R1 are in AREA 0 (X & W
networks).

Q) Is it normal behaviour that even if we do
redistribute-connected with summarization that it will
only get propagated to external ASs and NOT within any
intra/inter areas?

I am finding this to be true, it makes sense. I would
like confirmation.

Cheers,
Sage
