Hi group,
Thanks a lot for all your reply about this issue.
I also percept that Summary-address can be used in summarizing from
external routes into OSPF, I ask this question becasue I have read the
following link, which states the usage of "summary-address"
http://www.fatkid.com/html/501_expert_redistribution.html
You an see that it use "summary-address" to advertise a FLSM into RIP in R3
and R4, also, R4 use this advertise into IGRP. Even the following link has
mention this type of usage for "summary-address":
But I cannot make it work in my LAB environment.
Can any experienced OSPF guy reply whether this usage of "summary-address"
is available or not? or the links above is wrong?
Thx,

PM Subject: OSPF to RIP
Hi group,
I am evaluating one of the OSPF "summary-address" function, I use in
"reverse" direction:
Scenario as following:
E1--R1--Ser0/0.2
R1 loo 12: 10.100.100.12/25
R1 E1: 10.100.1.1/24
R1 Ser0/0.2: 10.1.2.5/24
Router rip
network 10.0.0.0
Redistribute ospf 77 metric 2
Router ospf 77
summary-address 10.100.100.0 255.255.255.0
network 10.1.2.5 0.0.0.0 area 0
network 10.100.100.12 0.0.0.0 area 0
I would like to make OSPF route 10.100.100.0/25 redist into RIP, as it's in
/25 subnet mask, I doing "summary-address 10.100.100.0 255.255.255.0" in
order try to change the 10.100.100.0/25 to 10.100.100.0/24 while redist
into RIP.
Can this be achieved? I see some documents mentions this but I cannot
implement it successfully.
Thx,
