Under your 2 loopback put " Ip ospf network point-to-point" That will cause ospf to see them as /24 not /32's as they are now. Since rip is using the same mask as the loopbacks, your redistribution should work without a summary.
Thanks Larry -----Original Message----- From: Timothy Ouellette [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 18, 2002 4:16 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: OSPF/RIP w/ Summary address. Serial connection between r2 and r1 is hdlc on the 141.108.1.0/24 network with RIP running on it for both r2 and r1. R1-->R3 and R1--> R4 are running OSPF in area 0. Generating the 141.108.3.0/24 from lo0 on r4 and 141.108.4.0/24 from r3. r2 ---141.108.1.0/24 ---r1 ------ 141.108.255.0/30-----r3 \_______ 141.108.255.4/30 ---- r4 What i'm trying to do is get the 141.108.3.0/24 and 141.108.4.0/24 to show up on r2 as rip routes heard from r1. I'm redistributing ospf 1 into rip with a metric of 5. Since r1 is considered a border router because it's connected to another protcol I figured I could use the "summary-address 141.108.3.0 255.255.255.0" command to generate a summary address to r2. This did not work until a put a static route to null0 for that particular network and then it showed up. r2#r 141.108.0.0/24 is subnetted, 3 subnets C 141.108.1.0 is directly connected, Serial0 R 141.108.3.0 [120/1] via 141.108.1.4, 00:00:22, Serial0 R 141.108.4.0 [120/1] via 141.108.1.4, 00:00:22, Serial0 150.150.0.0/24 is subnetted, 1 subnets C 150.150.150.0 is directly connected, Loopback0 My understanding of the summary-address command is to normally take external routes and summarize them into OSPF but maybe I'm using it backwards in this case to solve the my issue. I would have also though that there would be the same /24 route installed in the rest of the OSPF routers but it is not there (atleast not as a /24) or in the ospf database. r4#r Gateway of last resort is not set 141.108.0.0/16 is variably subnetted, 5 subnets, 3 masks C 141.108.255.4/30 is directly connected, Serial0 O 141.108.255.0/30 [110/128] via 141.108.255.5, 00:09:10, Serial0 C 141.108.3.0/29 is directly connected, Loopback0 O 141.108.5.0/28 [110/129] via 141.108.255.5, 00:09:10, Serial0 O 141.108.4.0/28 [110/129] via 141.108.255.5, 00:09:10, Serial0 r4# I would have thought it would show up on R4 and R3 but only the /28's are. Below is the config of the router with the redistribution and the summary-addresses. Is there another way to do this with multiple ospf processes too or any other tricks you folks may know? r1#sr Building configuration...
