Well since I need the redistribution practice, figured I'd plug your config into my pod and see if I could figure out what gives!
First thing I noticed...and it may just be a typo or dyslexia (it's an affliction I experience often (smile))if you didn't cut and paste your configs. >From your post... A is connected to B with 10.1.1.100 / 24 - Serial 0 B is connected to A with 10.1.1.1 / 24 - Serial 0 B is connected to C with 192.168.1.17 /28 - Serial 1 doesn't coincide with your posted configs hostname RouterA ! interface Serial1 ip address 10.1.1.100 255.255.255.0 clockrate 64000 hostname RouterB ! interface Serial0 ip address 192.168.1.17 255.255.255.240 no fair-queue ! interface Serial1 ip address 10.1.1.1 255.255.255.0 Second...Here's my plugged in config and all devices have connectivity to all other devices as expected. Caveat: only the necessary portions of the config are listed for brevity and I changed some DTE/DCE interfaces and increased the clockrate (personal preferrence)! hostname RouterA ! interface Serial0 ip address 10.1.1.100 255.255.255.0 no fair-queue ! router ospf 100 network 10.1.1.100 0.0.0.0 area 1 ! end ! hostname RouterB ! interface Serial0 ip address 10.1.1.1 255.255.255.0 no fair-queue clockrate 4000000 ! interface Serial1 ip address 192.168.1.17 255.255.255.240 ! router ospf 100 network 192.168.1.17 0.0.0.0 area 0 network 10.1.1.1 0.0.0.0 area 1 ! end ! hostname RouterC ! interface Serial0 ip address 192.168.1.18 255.255.255.240 no fair-queue clockrate 4000000 ! interface Serial1 ip address 192.168.2.49 255.255.255.240 clockrate 4000000 ! router ospf 100 redistribute igrp 200 metric-type 1 subnets network 192.168.1.18 0.0.0.0 area 0 default-metric 10 ! router igrp 200 redistribute ospf 100 network 192.168.2.0 default-metric 10000 100 255 1 1500 ! ip route 192.168.1.0 255.255.255.0 Null0 ! end ! hostname RouterD ! interface Serial0 ip address 192.168.2.50 255.255.255.240 no fair-queue ! router igrp 200 network 192.168.2.0 ! end HTH Stefan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Hunt Lee Sent: Friday, December 07, 2001 2:35 AM To: [EMAIL PROTECTED] Subject: Redistribution Question [7:28374] I need some help on a Redistribution question: I have setup 4 routers: Router A - Router B - Router C - Router D A, B & C are running OSPF, and C & D are running IGRP - I'm trying to redistribute between OSPF & IGRP routes: A is connected to B with 10.1.1.100 / 24 - Serial 0 B is connected to A with 10.1.1.1 / 24 - Serial 0 B is connected to C with 192.168.1.17 /28 - Serial 1 C is connected to B with 192.168.1.18 / 28 - Serial 0 C is connected to D with 192.168.2.49 / 28 - Serial 1 D is connected to C with 192.168.2.50 / 28 - Serial 0 However, I could only ping from D to A (& vice versa), but I couldn't ping from B to D, or D to B N.B: D to C (and vice versa) is fine as they are directly connected Any help will be greatly appreciated.
